MrMenCentral (h≡r) likes to include conjoined twins (also known as Siamese twins) in his Homestar Runner fanon.
- The CatDog Coaches were conjoined as a result of The Virus. h≡r decided he would like to keep them that way, so they weren't separated at the end of virus 2.
- The Twins used to be conjoined twins before their first appearance. It is later revealed that they were separated by Coach Q.
- They also used to have conjoined Siamese cats (a play on Siamese twins). The cats' names were Skippy and Jon, a reference to Skippyjon Jones.
