Mystery Comedy with Pizza from 90s

So we’ve been wracking out brains. We’re looking for a movie that has a scene in it where a girl with dark hair is eating pizza and then sucks and twists all of her fingers to get the grease off. The scene is so weird and lasts forever. We believe it came out in the 90s. Maybe the 80s. We thought it was Drop Dead Fred, but nothing is coming up on our searches. Can anyone help? Pleeeeeaaaaase. Thank!
