Plastic Underwear is the twenty-eighth Butterfinger commercial featuring The Simpsons that first aired on December 31, 1999.
Plot[]
Lisa bites into her Butterfinger, awakening a sleeping Grampa. When he attempts to go back to sleep, the biting noise happens again, though this time it's not Lisa but Grampa's plastic underwear. Once Grampa is back sleeping Lisa once again bites her Butterfinger.
(Originally, Grandpa was mentioning that it was his osteoporosis, but he was overdubbed in this version)
Trivia[]
This is the only Butterfinger Commercial Bart doesn't appear in.
The commercial aired the same day the SpongeBob SquarePants episode "SB-129/Karate Choppers" premiered on Nickelodeon.
