Hulk Hogan
After Rocky III co-stars Hogan and Mr. T tag-teamed at the first Wrestlemania, Hogan teamed up with the rest of the A-squad to take down mobsters trying to close a youth center in the 1985 episode "Body Slam." Coincidentally, Dirk "Faceman" Benedict would make a wrestling movie with the exact same title the following year.

Boy George
How Boy George achieved the success he did in the 1980s, what with him getting confused with country music act "Cowboy George" all the time, we have no idea. We experienced total mind-melt watching the gender-bending synth-pop singer help the A-Team find a missing sheriff after getting booked to play a show in Texas by mistake.

Rick James
When Rick James is worried about you, you know you're in trouble. To help out his convict friend (played by Isaac Hayes!), James sneaks the A-Team into a corrupt prison as his roadies when he puts on a show.

William "The Refrigerator" Perry
Not only was the Fridge a member of G.I. Joe, he was also a member of the A-Team! At least, he seemed to know B.A. Baracus and returning guest star Hulk Hogan when they ran into each other at a hospital. We like to imagine he hurt his foot stopping an evil land baron with the guys.

Pat Sajak
Howlin' Mad Murdock may be howlin' mad, but he's howlin' good at wheel of fortune, and actually goes on the show and wins a trip to Hawaii. In between tapings, Murdock is kidnapped and forced to steal a Russian helicopter. Sajak has nothing to do with the helicopter plot, but I'm sure he would have helped, had he been asked.

Bonus: Tia Carrere!
Okay, so she wasn't playing herself, but in the Season 4 finale, the A-Team helped a general find his half-Vietnamese daughter, played by the young Wayne's World star, and after kicking all their asses (with the help of a clearly male stuntman) she helped them rescue her dad. Carrere was actually supposed to join the team full-time in Season 5, but the show was re-worked, and she was replaced with a male character -- probably because the regulars never liked having a girl on the show.
