Tax forms make me crazy, at least to the point where I'm talking to myself. I wasn't eavesdropping or anything, but I did overhear parts of the conversation, and this exchange struck me as funny. (of course, the inappropriate biblical pun built into the word "eavesdropping" also made me laugh, so let's not use me as a standard of what's funnny right now)
Oops. Shouldn't have filled in line 24 - that's for blind people.
