Do a Google image search on Aunty Acid.

Be prepared to spend some time looking at the cartoons because I personally find it addictive. Sometimes I open the Google image page for Aunty Acid when I am at work, especially if the nearby yakkety-yakkers are in overdrive. The pointed relevance of the cartoons make me laugh but also act as an antidote to some other people's annoying habits.
