The song "You Know My Name (Look Up The Number)". It's like a comedic vs. of "Revolution #9", but as a John and Paul collaboration and much more enjoyable. Includes Paul as "Dennis O'Dell."
"Why Don't We Do It In The Road", arguably the dirtiest and simultaneously funniest thing Paul ever did during his time with the Beatles.
For "Oh! Darling," Paul went into the recording studio before the other Beatles would show up for days on end to try and nail the raw vocal performance he wanted in one take. And to have fun with the tape delay, judging by this outtake. Oh, the delirium of it all!
Paul: Experiments of a due nature being carried out on rats. And people... and rats. And ratty people. And people-y rats.
The outtakes from "No Reply" on the Beatles Anthology collection. Basically they keep singing "YOUR FACE!" over and over again instead of replacing it with a different lyric each time, resulting in some hilarious combinations.
Also an outtake from "I'll Be Back." After Lennon finds he can't sing in the current key, he continues singing like he's completely drunk.
"Only A Northern Song", if you listen to the lyrics.
"If you're listening to to this song, you may think that the chords are going wrong, but they're not, we just wrote it like that"
"Drive My Car", especially the climax:
"I got no car, and it's breaking my heart But I found a driver, and that's a start"
