Trivia[]
- Although Sheldon (who frequently tends to exaggerate or even outright lie about his childhood on TBBT) has claimed that Billy was one of his childhood bullies, events involving Billy that were seen in Young Sheldon appear to disprove those claims as he's most often merely seen being clueless and dimwitted, often having little idea what goes on around him most of the time.
- Despite initially acting like a bully, over the course of Young Sheldon he's become more happily dim-but-harmless, and even seems to like spending time with Sheldon on occasion. His sister Bobbi Sparks is the only one who is bullying Sheldon.
- Billy has been shown to be slow/dimwitted as evidenced by multiple scenes in the show like when his mother said that whenever his Spanish teacher would say "si" Billy would respond by saying "See what?".
- Billy did ask out Missy in season 5, but she turned him down. The only reason why she turn him down in middle school and high school was because that appearances are everything. Missy is very pretty and being seen with Billy Sparks isn't going to help her social life. Billy gave up asking her out. Billy and Missy decided to stay friends when George Sr stopped Billy from asking her out because Missy would reject him.
- According to Sheldon in a voiceover in Season 6, after passing his test where he got a 68, he went on to 7th grade and ended up staying there for several years.
- Despite McClure being billed as a main cast member since Season 5, Billy continued to appear infrequently. He was only listed as such in the episodes that he appeared in, similar to Jeff Difford.
