I only recall one episode where he got a pie in the face. It was a nice buildup where he was making bad puns.
Geoff: (talking with a bad accent in a Jerry Lewis-like voice) I'll tell ya what you really won.... it's a ROLLS ROYCE! (taking out a box of rice) Here's the ROYCE! (taking out a bag of rolls) and here's the ROLLS! (laughing maniacally)
Jan: You asked for it Geoff! (She pelts him in the face with a pie)
Geoff: (trying to talk with pie on his face) Ok... I've kidded you long enough... Now to get serious, and tell you what you REALLY won... You have won... A WASHER! (takes out a plumbing washer) and Dryer, which is right over there!
The curtain opens to reveal a washer and dryer, and Geoff runs over to Jan, trying to kiss her with pie still on his face. Jan looks as if she's not expecting this, so this was likely a great unplanned moment.
As for the "punching" incident... it wasn't exactly like that...
Geoff gets hypnotized by a genie (the late Johnny Jacobs, in a rare on camera appearance) and when Geoff goes into a trance, the contestant seen is hitting Geoff in the face with a large bag of money. Definitely one of the weirdest skits on the show.
Geoff was rarely a "victim" of slapstick-like stunts. Usually, the contestant was the one being pulled through the wringer. To a contestant, the show was like a roller coaster ride. All she had to do, figuratively, was strap herself in, and watch the mayhem, and maybe win a decent prize.
One blooper seen on various blooper shows is Geoff losing his composure when talking to a contestant with an alligator hat. Geoff told me about that moment. Quite simply, he couldn't help but think that, here he was, a TV personality, and he's talking to someone with an ALLIGATOR on her head!
As for the guard, Emile Artouri, whom never cracked a smile, despite Geoff's valiant efforts, he was only allowed to say "Yes, I did" when Geoff asked if he hid the check. However, there were a couple occasions when he broke this rule. Once, Geoff asked him if he hid the check, Emile looks around and asks "Where's the cue card?" (As a security measure, the show never used cue cards, in fear that someone would find out, and attempt to steal the prizes) and Geoff lost it. Another time, Emile muttered something else unintelligible that only Geoff heard.
