I was watching the Andy Dick show and during the sketch where Vitamin C and him are working on a song he tells her to sing from her diaphram then tickles her stomach,she screams. Kinda quick but it was cool.
It was on "Jackass Sunday Night" on MTV I think it was either before Sunday Night Heat or it was the new one after Jackass. I'm not sure when it will be on again but they sometimes show reruns of Andy Dick before Heat on sunday also MTV is always playing their shows over and over again so you should see it.
Tune in to mtv at 9:00 or 9:30 to see the andy dick show. I am not sure if this is the one were she is tickled so if you are interested watch mtv the andy dick show to hopefully see Vitamin C get tickled.
But don't get your hopes cause i could be wrong so tune in and see if it happens.
