Alice's appearance in 'Waynes World' must rate as one of the most well-known cameo appearances in movie history. It's where the 'We're Not Worthy' phrase came from taht he's probably heard a million times by now. The movie is based on a comedy skit from the US 'Saturday Night Live' TV series, played by Mike Myers and Dana Carvey. During the film, the main characters, Wayne and Garth, travel to an Alice Cooper show and get to meet with him backstage, uttering the immortal words 'We`re Not Worthy!'

"The scene was filmed near the end of the 'Hey Stoopid' US tour. Eric Singer had begun working with Kiss so Jimmy DeGrasso was the drummer at the time. It was all shot backstage at Universal Ampitheatre in Los Angeles. The backstage filming didn't take very long, the concert footage took longer. During one take of Alice's history lesson on Milwaukee, Dana Carvey as Garth broke into a Johnny Carson, "I did not know that", which was very unexpected by everyone and very funny. The thing they were doing to crack up Alice was when they would do the "We're Not Worthy" bit, is they would expound it into "We're not..." (fill in the blank with every imaginable insult you can think of)."
(Renfield, May 1996)

Alice item from 'People Weekly' From the May 4, 1992 ('Chatter' column):
A funny thing keeps happening to Alice Cooper since his cameo in the hit movie 'Wayne's World'. Cooper, 44, who lives in Scottsdale, Arizona, says that now when he goes to movies or a 7-Eleven, fans make like Wayne and Garth, going overboard on paying him homage. "Somebody says, 'Hey, Alice,' and it immediately starts: 'We're not worthy, we're not worthy!' Every place I go now, same thing," says Cooper. "I was at a [Phoenix] Suns [basketball] game, and there was a whole section going, 'We're not worthy, we're not worthy!'"
How does Cooper feel about all this fan appreciation? "[My] last album was titled 'Hey Stoopid'. So for a year I had to hear 'Hey, stupid!' This is better."
