This one's making the rounds on reddit. Fran Drescher using her "real voice" in a scene from The Nanny. YOU MEAN THAT WASN'T HER REAL VOICE????!?!?!
It also includes a wasabi-tasting gag, pretty edgy stuff in 1997! Enjoy!
"So what's it like working with Maaaaaahvin Hamlisch????!??!" If I remember correctly, this also happened to Balki in an episode of Perfect Strangers.
