A good deal of the people who "only appear on a Vh1 countdown or of the like type of show" are really funny people who don't have enough coverage yet. (though I haven't a clue who you're talking about specifically)

- People who rely on thier gimic too much
- People who think just making funny faces is good stand up material
- Peope who release a cd, do four comedy specials, and tour for seven years all with the same 30 jokes.
- The entire Blue Collar Comedy tour
