Crank Yankers
If you missed it and/or won't be able to watch when it is on again, you can see the call that he was on here:

The link will probably break so you might have to copy and paste a time or two. Or you can go to

and click on the one that says "CY: Billy Fletcher overwhelms an unsuspecting restaurant"
He didn't really do much, it was a little bit of a disappointment. But the one on the 16th is supposed
to be him on a call by himself. Hopefully there'll be even more in the future. Snoop is on all the time and is hysterical most of the time.
