This month we're taking a look at celebrities who did TV commercials.

Whenever you get into any profession, you have to start at the bottom. The TV business is no exception. The stars you see in prime time today probably cut their teeth working in TV commercials. Heck, some of them still do TV commercials even after they become big stars (but it's often overseas...shhhhhhhh).

After the jump, a sampling of TV commercials from years ago that star celebrities who are now household names. If you're old enough to remember these commercials, you'll probably say to yourself, "Oh yeah, I remember this ad, but I didn't realize that he was in it!"
