Mike Myers thought he was being fired from 'Saturday Night Live' "every week".
The 51-year-old actor was so desperate to remain on the late-night TV sketch show - which he was a featured performer on from 1989 to 1995 - for as long as possible that he ended up constantly fearing he would get the sack.
He said: "I thought I was being fired every week. I'm not exaggerating. Lorne [Michaels, show creator] keeps saying to me, 'Stop saying that,' but it's true! You just never wanted to blow it.
"I loved having an idea in the bath on a Sunday and then seeing it on national TV on the following Saturday."
Mike admits he got star-struck when he started appearing on the programme and couldn't believe it when then-host Steve Martin paid for the whole crew to have lunch and then invited him to go out chewing gum shopping.
He said: "I remember Steve Martin was the host and I couldn't believe when he was talking to me.
"I was like, 'Wow, those are the molecules that Steve Martin's made of.' He invited us all out for lunch, he paid for us and then said, 'I'm going to go get some gum, you want to come with me?'
"I was like, 'Yeah!' People were like turning around in the street and nudging each other and I went into a variety store and he bought gum. I'll never forget it the rest of my life."
But Mike did also have his bad days connected to the show such as when he burst out crying after finding out from a reporter that his "hero", fellow 'SNL' star and comedienne Gilda Radner, had died.
He added to The Hollywood Reporter: "She was my hero. She actually passed away on the last day of my first half-season. It was very sad.
"This reporter asked me, 'What did you think of Gilda Radner?' I had no idea she died - this was before CNN - and he told me. I started to cry in the lobby."
