(Strip Number 4304, Original Publication Date, 1 March 1983)
Panel 1: We start things off with Mike in the tub playing with his toys and yelling "Hyahh!!! Enemy approaching! Blast'em, Shark Man!"
Panel 2: He then says "They've seen our submarine, Captain! DIVE!!"
Panel 3: Elly comes in, points the Finger of Judgmental Hostility at him and tells him that despite having been in that bath for an hour, he's still filthy.
Panel 4: Mike frowns the Bulgy-Eyed Frown of Confusion and says "You didn't tell me that this was a washing bath!!!"
Summary: The Lynnsight in the book tells us that this is a distinction Aaron made. What it also tells us is that Lynn has no real problem with using her strip to complain about things that her family does that confuse and annoy her and, given how breezily she blows them off, they're supposed to sit there and take it.
