| 1 | My Favorite Martian (1963) ended after three years, because the people at the top killed the goose that laid the golden egg. They didn't know how to keep the goose alive. |
| 2 | (on being labeled a character actor) I'm an actor and that's it -- period. Producers and studios have thrown many things at me over the years: comedy, tragedy, drama, drawing-room comedy. I've managed to keep my head above water in most of these genres, but I don't put myself in any one category like "comic actor" or "musical-comedy" actor. |
| 3 | (his 1995 Emmy Award acceptance speech) I have 30 seconds to tell you I have been waiting 60 years to get on this stage. |
| 4 | (on his thoughts after four episodes of My Favorite Martian (1963)) I thought, "What am I doing here? I'm running around with two pieces of wire coming out of my head. I must be crazy.". |
| 5 | I never should have done My Favorite Martian (1963). I didn't work in television or film for three years after. Everyone thought of me as a Martian. Do you know what it's like to go to Madrid, Spain, on vacation and have a guy yell out, "Hey, Martin!" and put antennas behind his head? When that happens, you know your career is dead. |
