(Strip Number 854, Original Publication Date, 14 May 1985)
Panel 1: We find Mike at his school library asking his friends what's short and round (the original has 'fat') and sounds like a leaky inner tube.
Panel 2: Since he's talking louder than a whisper, the short, round and-or fat school librarian shushes him loudly to the delight of him and his friends.
Summary: While it's clear that said friends are going to sell him out in a heartbeat, what bothers me is that Lynn is going to boast about a change in dialogue instead of wishing she could change being a stupid little jerk to authority figures.
