6. Mark Wahlberg - Entourage
Episode Appeared: Pilot (Season 1) I should mention that Wahlberg makes several cameos across the entertaining run Entourage had but the only one we're going to discuss here is the first one. I noticed his cameo right away and I had to lunge for my remote to rewind and then pause. I sat there, on my uncomfortable couch speaking out loud to myself "Is that... is that Mark Wahlberg? IT IS!" Then I continued watching but I never forgot how awesome it was. I stopped watching Entourage at some point. Perhaps I should finish it out...
