I drew the mocking child in afterwards and couldn't figure a way to fit her in without making the strip unnecessarily long. In the end we felt that Dave's shame was obvious enough without the use of the heckler prop.
Don't forget to go to
threadless.com and buy
finkenstein's Cookie Loves Milk shirt. It's been reprinted and comes in pink and manly blue.
EDIT: In case you don't know what I'm talking about, see the strip at
