Parent's evening at school. Dad is listening to the teacher, but Mum is distracted by a talking biscuit putting the moves on her. "I saw you checking me out..." and so on. So when the teacher asks her something inaudible (possibly "we're planning to sell Tommy to a white slavery ring and use the money for a new gynmasium, is that all right?") she says yes with her mouth full.

Surprised that one aired more than twice, actually, but it's still being used.
