Stand-up comic/ventriloquist Jeff Dunham chose the golden retriever, Bill, for the family pet, but his wife chose a chihuahua, Rusty, "a yapping beanie baby" "the richard simmons of canines" according to his observations in his comedy special available on dvd, Spark of Insanity (2007).

He and his wife actually have three chihuahuas who all sleep in the bed with them, a little girl named Darby and boy Jake. Rusty likes Jeff best, and if Jeff and his wife have an argument, in the middle in that night Rusty pees on the misses.

So of course Rusty became intrical to Dunham's routines. Among the extras on the dvd is a short-short film starring Rusty, embedded below.
