Every once in a while I like to cut out the wordiness and do a very brief single-idea gag like this. Breaks up the routine.
I should note another rule-break with a change to the art in this one. Originally you could see her feet and I chopped them out so it could be more of an ambiguous pose between “exhausted doing push ups (or ‘girl’ push ups)” and “on the barroom (or dorm) floor.” I’ve been a lot freer with the art alterations lately. I’d almost consider that rule optional any more.
