I don't know if anyone else ever saw the one for "Butt Crack Spackle". When I first saw it I had to make sure I wasn't watching SNL, and I wasn't. Then my mom saw it and thought it was a joke too, but I pointed out to her that it was a legitamate phone number and adress. OMG

Speaking of SNL and annoying commercials, a few weeks ago I saw an episode where there are two hunters sitting in the reeds waiting for a duck. One starts talking to the other about his insurance policy and the AFLAC Duck shows up and they blow him out of the water. After that they are bored since no other prey has shown up, so the other goes "I think I need to make a collect call" and Carrot Top shows up with his phone and they blow him out of the water.
