Vice's Jamie Lee Curtis Taete went to the new Bill and Ted's Excellent Halloween Adventure show at Universal Studios and saw some "comedy" that wouldn't have been out of place in the bad old homophobic 1960s:

Anyway, Superman joins Bill and Ted on their witch-killing quest. Bill and Ted are pretty psyched about that because, y'know, he's Superman and he's really useful to have on your side in a battle against evil witches.

But then, uh oh, a witch accidentally sprinkles Superman with fairy dust, turning him gay...After becoming gay, Superman's voice and posture changes. His lips purse, his toes point inward, and his wrists become limp. His new voice sounds like a homophobic uncle doing a drunken impression of Richard Simmons, complete with lisps and frequent use of the word "faaaaaaabulous!"

Bill and Ted, understandably, are bummed. Their initial excitement at having Superman with them on their quest turns to disappointment as, obviously, now that Superman is gay, he is not going to be of any use to them. "Who could possibly make a worse Superman?" asks Bill. "Ben Affleck?" responds Ted.

Thankfully, Robot 6 reports that Universal Studios has cancelled the show. The site for the show now simply reads:

After thoughtful consideration, Universal Studios Hollywood has made the decision to discontinue production of the Halloween Horror Nights' "Bill & Ted" show for the remainder of its limited run.
