Ever since Audience Participation became an integral part of showings of The Rocky Horror Picture Show, the funniest parts of a performance are usually audience members shouting out something that changes the meaning of the subsequent line in the movie. Perhaps the best example is where Frank says the word "spark" in an especially dramatic way, in a British accent with the "r" dropped. Result: this line is almost always preempted with "Who gives the best blowjobs on the Enterprise?" or something similar.
note What's white, sells burgers, and rhymes with asshole?Didn't we see a castle a few miles back?
"See androids fightingnote AND FUCKING, AND SUCKING ON Brad and Janetnote 'S TWAT! Anne Francis stars innote DEEP THROAT, THE SEQUEL TOForbidden Planet"
note DESCRIBE THE WHITE HOUSE!"Must be some sort of hunting lodge for rich weirdos."note RICH WEIRDOS AREN'T IN SEASON, ASSHOLE! (TELL THAT TO SARAH PALIN!)
"And crawling note WHERE? on the planet's face note WHAT ARE DISCO PEOPLE? some insects note WHY IS YOUR PHONE BILL SO HIGH? called the human race note OH SHIT, THAT'S US!note WHERE'S YOUR NECK? Lost in time note NAME AN OLD TV SHOW! and lost in space note WHAT DOES THIS FILM LACK? and meaning."note DON'T FORGET TO TURN OFF THE GLOBE!
Riff's constantly stoned demeanor provides a number of moments.
note Nah, that's just Mediocre Scott. Great Scott can walk.
The Incredibly Lame Pun is further compounded by the Audience Participation for this linenote they throw toilet paper at the screen — as in Scott Tissue, making it a three-way pun.
"On a night out." "IT WAS A DAY'S INN!" "It was a night out..."
"I think perhaps you better bothnote FUCK OFF! ...come inside.note I DON'T CARE WHERE YOU COME, AS LONG AS YOU CLEAN IT UP! (I DON'T CARE WHERE YOU CLEAN IT UP, AS LONG AS YOU COME!
Brad: You're a hotdog,note UP MY but you better not try to hurt her,note WITH YOUR TWO-INCH Frank Furter. (gets Medusaed) Dr. Scott: You're a hotdog,note UP MY but you better not try to hurt her,note WITH YOUR TWO-INCH Frank Furter. (gets Medusaed) Janet: You're a hotdog— (gets Medusaed) Audience: Don't worry, it wouldn't have rhymed anyway!
At one point, when Dr. Scott is being magnetically dragged up to the lab, he winds up in Columbia's room, and circles around her and Magentanote RING AROUND THE LESBIANS!, who barely even give him a glance when he's gone.
"Once in a While," a Cut Song. It's a very somber moment, almost tearjerking...and then you see Frank in the background, taking a postcoital snooze while still dressed in Janet's nightgown.
The Criminologist doing the pelvic thrust during "Time Warp".
"...And that's just one small fraction note TWO INCHES! of the main attractionnote THREE INCHES ."
Throughout most of the song "Eddie's Teddy", Frank has this very bored expression on his face, which just seems so wrong and hilarious at the same time. Everyone's singing about a character that he just killed a few scenes earlier, and Frank looks like he could not care less.
Conversely, Frank going completely off the rails chasing Rocky during "Sword of Damocles".
In some performances, the rubber gloves that the audience snaps along with Frank during his speech are rubbed to make an obnoxious squeaking sound as Rocky fondles Janet's breasts.note If you couldn't figure it out, it's implying that Janet has fake boobs.
In the 2015 broadcast of the stage play, there are a few funny moments:
Frank choking on a pubic hair while trying to say one of his lines during Brad's bedroom scene.
Frank accusing Brad of sleeping with Rocky.
Columbia reaching a high note during Eddie's Teddy, which causes her to break glass, causing the rest of the characters to stare at her.
Mel, one of the narrators, eating a red velvet cupcake.
A scene similar to the Rocky Roll Call, except instead of saying the names of everyone who is in the Role Call, the characters scream as each of them gets the bag with Eddie's remains in it.
Columbia's silly dance routine she does when being sprayed.
