Glossary of genitalia slang pairings

[mothwentbad]

Ok, I've noticed that some slang words for genitalia tend to occur together. I'm going to try to make a list here, and you can help me out. No mixing and matching is allowed ever, people:

penis and vagina
dick and pussy
cock and cunt
shlong and cooter
Johnson and the beaver
candle and snuffer
porpoise and hoop
Captain Salami and the Magic Sausage Slot
Smaug the one-eyed dragon and The Cavern of Animosity
The Meat Wraith and The Alley of Unspeakable Horrors
Havoc Gladius and The Sheath of Despair

...I'm going to stop now.

I've tried to do same-sex pairings, too, but all I've got is...

Johnson & Johnson.

Well, you know where my head is at, anyway.

Added to the list:
The Interrogee and the Chamber of Endless Contraction
Rod and hole
Dangling chad and ballot box
Tab and slot
Spoon and cauldron
Plug and outlet
