Richard Dean Anderson (1950- ) is an American actor best known for two particularly geeky roles: originating the role of Gadgeteer Genius Angus MacGyver on the 1980s MacGyver series, and for playing Colonel, later General Jack O'Neill in the Stargate-verse TV series beginning with Stargate SG-1, which he also executive-produced.
- Bunny-Ears Lawyer: Conversed. While he was playing Jack O'Neill, General Michael E. Ryan, the real Chief of Staff of the Air Force at the time, did a cameo As Himself on the episode "Prodigy". Anderson later recalled asking Ryan if he had colonels as disruptive and irreverent as Jack, to which Ryan replied, "Son,note yes, we've got colonels like you and worse." Anderson then goes on to say that Ryan's successor John P. Jumper agreed: "You're doing the kind of thing we all want to do but really can't."
- '80s Hair: His iconic mullet from MacGyver certainly comes to mind.
- Ink-Suit Actor: His talking head as Killian Darkwater in Fallout is basically MacGyver without the mullet.
