Ok.....this could be fun. This stems from something a co-worker from years ago and I used to do. Just sit around and try to think up obscure "once upon a time" celebrities....ones that are (virtually) unheard of now, or although once in a "big" part, are now doing nothing but bit parts in B movies (although not limited to cinema).
Ok.....some may turn out to be successful, just not in the mainstream (no teasing others because they didn't realize). For example....when I used to play with Charlie (old co-worker) I once said "Meathead from All in the Family"....he says "you mean the ultra-famous director, Rob Reiner?". Ok...no teasing others (like me), got it?
Some are the obvious ones you hear jokes being made about all the time (Danny Bonaduce, Any American Idol, etc...). Let's TRY to come up with more obscure ones.....ones we will get a giggle out of remembering...and of course get a laugh AT them now!!
Ok, I'll start with a few:
Hal Linden (aka Barney Miller)
Ron Palillo (aka Arnold Horeshack from Welcome Back Kotter)
Gabe Kaplan (Kotter)
Buster Poindexter (Hot, hot, hot)
