Last week’s best ad libitum:
(Scene: 70 year seven kids after lunch listening to Science-Talking Guy (me). There is one Irritating Kid sitting in the front row. You know the guy. Probably went to school with him. Smart-arse twerp who won’t shut up. Science-Talking guy fills a plate with shaving cream from a can.)
Irritating Year Seven Boy: Oh sir! Put some in my hand! Put some in my hand!
Me: Why? Do you have hairy palms?
Boo yeah.
