Do You Ever Take on Odd Jobs for Extra Cash?

Pretty self-explanatory discussion here! What kind of odd jobs do you or would you take on to earn some extra cash?

One summer, I cleaned my neighbor's house once a week to the tune of $20/an hour. Kinda a gross job as he was a single dude and a farmer so I would sometimes find gross surprises in the sink...like a kidney from some animal he had butchered! It really wasn't bad, though, and he kept his bathroom really nice, which is a total bonus when it comes to house cleaning.

I just recently took on a job to pet sit for my boyfriend's parents while they're away on the east coast. In exchange they're going to pay for a some airline tickets for me this fall! Talk about a deal, I stay here for free and take care of pets in their amazing house AND get to visit my family and boyfriend while he's away at school.

So tell me about your experiences! Gross, good, bad, funny...I want them all!
