Sheldon Oswald Lee is Jenny's geeky friend and admirer.


Sheldon made his debut appearance in "Attack of the 5½ Ft. Geek".


Sheldon is a 5-foot 6-inch tall (as noted in "Attack of the 5½ Ft. Geek" ) teenage boy. He is 16 years of age through seasons one and two, but is technically 105 after season 3, episode 2, "Good Old Sheldon". Sheldon is depicted as a minor slob, with greasy black hair, and two spots on his cheek that could either be freckles or acne. His hair has two cowlicks at the crown of his head, and he is shown to have crooked/sticking out teeth. He is usually dressed in blue-gray pants, a white T-shirt, and an auburn hoodie.


Sheldon is "geek" stereotype, heavily invested in both science and comic book culture. His major character trait is his obsessive crush on Jenny. It is shown in the episode "Designing Women" that he has a shrine for her, and it is said in "Agent 00' Sheldon" that he stalks her. Despite the extent of his affection, he never is able to get Jenny to go out with him, and the two are simply friends. Whilst normally sweet-hearted and intelligent, Sheldon easily becomes jealous.

Sheldon is also a budding engineer, and often invents useful gadgets for Jenny in the hope of impressing her (although she usually doesn't accept them). He also created The Silver Shell, in an attempt to show Jenny that robot boys would not be good for her, but this backfired when she actually fell in love with The Sliver Shell (though, after a while, she grew to hate SS when he ruined her first dance).

He seems to like reptiles, as seen in "Shell Game". He is also the fastest member of the swim team.


Jenny Wakeman

Despite not returning Sheldon's feelings for her, Sheldon remains one of Jenny's closest friends. Jenny sees Sheldon as a smart guy who can always lend a helping hand, although can sometimes get himself into trouble. Jenny also relies on Sheldon to fix malfunctions that her Mom is either too busy or unable to fix.

A common misconception is that series creator Rob Renzetti supposedly confirmed that Sheldon and Jenny would end up together had the series continued, due to Renzetti stating in an interview that he was rooting for him. However, in a later Q&A, Renzetti clarified that he simply meant that, being a nerdy person himself, he sympathized with Sheldon, and that he actually had no long-term plans for Jenny's love life, which he considered a minor part of the show anyway.[1]


Brad is one of Sheldon's friends. They are not as close as Brad and Jenny, but are still friendly, hanging out both inside and outside of school. and going on adventures together.


Tuck and Sheldon are rarely seen talking to each other on a regular basis. This may be due to Tuck being much younger and the two thus being in different levels of school.

Tuck orders Sheldon around in "Tuckered Out", riding him like a horse and complaining to him when things go wrong. Sheldon ultimately gets revenge by helping Brad and Jenny play home movies of Tuck to the entire town. Sheldon sells Tuck his time machine in "The Price of Love".

Dr. Wakeman

Both Sheldon and Dr. Wakeman care deeply for Jenny, and show concern for her well-being when she is in trouble. When Sheldon was 75 years old in "Good Old Sheldon", he flirts with Dr. Wakeman, much to Jenny's disgust. It can be inferred that Sheldon's crush on Jenny may stem from an older crush on/interest in her mother, or vise versa.


In "Designing Women", Vexus disguises herself as QT-2 (Cutie Two) in order to get XJ-9's master plans from Sheldon, who has a crush on QT-2. When Sheldon gets "Cutie Two" a drink, she removes her disguise to sneak out and take the master plan with her. Sheldon reveals to Jenny what he did, and Jenny uses one of his inventions to defeat Vexus, once again returning her master plan to her mother.

Don Prima

Due to being polar opposites, Sheldon and Don Prima are sworn enemies. Don Prima is a popular, good looking social butterfly, as opposed to Sheldon, who is a geeky social outcast.


Sheldon pays Pteresa to pretend to be his girlfriend in order to make Jenny jealous.


  • Sheldon is assumed to be of Japanese descent because of his similarities to the Japanese people in "Speak No Evil".
  • As revealed in "Price of Love", sometime within twenty years, Sheldon becomes a billionaire.
  • Sheldon created a time travel machine and sold it to Tuck for two cents.
  • In the Russian dub of season 3, Sheldon is voiced by a woman.
