Camp Gay: The angel was already flamboyant, but the riffing makes him out to be this.
Crow: Honey, is that a gay man on the Johnsons' roof? Servo: Should we get a gay man for our roof, honey?
Elton John and Charles Nelson Reilly references abound as well.
Celebrity Resemblance: The angel's passing similarity to Charles Nelson Reilly is all the license Crow needs to do endless imitations of the guy.note As Mike even notes in the Amazing Colossal Episode Guide, "if [Trace] had done it 4000 times, it wouldn't have been enough for me".
Fake Static: When the couple is pitching its completed song to the boss, Servo acts as if the office's speakerphone is going in and out, preventing them from hearing it.
Getting Crap Past the Radar: "Let's see... What rhymes with 'blue balls'?" How in the world did that get past censors? (Though Comedy Central had just as ribald material on some of its other shows at the time, possibly explaining the pass. However apparently it didn't pass the censors at Comet TVnote part-owned by the notoriously right-wing Sinclair Broadcast Group (who also own Ring of Honor): when this episode aired some of the lines in the short, such as the "Blue Balls" line, got muted out.)
The Gods Must Be Lazy: A few riffs point out the angels are more concerned with a married couple wanting to go on their honeymoon instead of, say, world peace.
Obfuscating Disability: Not "disability" as such, but Crow pretends to get pregnant because he thinks people bend over backwards to give pregnant women whatever they want and he's sick of them having all the attention to themselves.
Crow: Okay, okay, I'm not pregnant! HEY, everybody, I'm not pregnant! That means I don't get a big free ride! "Oh, my ankles are swollen! My back hurts! Carry me, I'm pregnant! Carry me!" Well, I want a cut of the action too, dammit! ... Who wouldn't wanna be pregnant, huh? Who wouldn't want to be a big load on the rest of the world? "Hey, everybody, I'm Queen of the World because I'm pregnant!" Then the whole world is supposed to bend over and smooch your ever-widening ass!
Mike: CROW! Crow, Crow, Crow...
Crow: Well, when is it my turn? When is it Crow T. Robot's turn? (*sobs*)
"Steve One, you go that way! Steve Two, come with me!"
"This has 'Steve' written all over it!"
*offscreen crash is heard* "Steve?"
"Oh, Steve's name is John!"
Re-Cut / Thanksgiving Episode: The MST3K version first aired as the grand finale of Comedy Central's traditional "Turkey Day" marathon, with host segments that tied into the framing sequences shot for the rest of the marathon (featuring Dr. Forrester and Pearl dealing with the guest characters the now-absent Frank invited for Thanksgiving dinner). Future airings had a completely different set of host segments, which still established the changes for the seventh season (i.e. Pearl Forrester moving into Deep 13).
