Fairly soon after his famous Cell match with The Undertaker, Mick Foley transformed from a sado-masochist with a ridiculously high pain threshold to a "human Muppet"... with a ridiculously high pain threshold. This led to an ongoing series of comedic moments for Mick such as:
The infamous "Mr. Socko" promo with a hospitalized Vince McMahon.
Pretty much every time he had a promo with The Rock after the Rock 'n' Sock Connection began, including the "This is Your Life" promo and when, as Commish, Foley finally got to pull a "IT DOESN'T MATTER WHAT YOU..." on the Rock which made even the Rock smile.
"The Rock thanks you for that."
When Mankind tried to cut a promo with the Rock and stepped on his catchphrases...
The Rock: [To Chris Jericho] You are exactly twenty minutes away...AND THE ROCK MEA-
Mankind: [Simultaneously] THE ROCK MEANS TWENTY MI-
The Rock: [Glares at Mankind] Don't you ever do that again, jabroni. [Barely keeps from Corpsing]IF YA SMEEEEEEEEEE-
His endless (joking) shots at Al Snow and Test in his books. He even poked fun at Snow in his children's book ("And Mick carried Al, as he would do for the rest of his life") and put a picture of Test in his second book with the caption "This was the goofiest picture I could find of him."
*His wife, Collette, upon hearing about a bad angle being proposed to Mick*: "[She] looked like she smelled a fart or saw an Al Snow match."
Made funnier by the fact Al Snow tried to pay back Foley's ribbing by ripping him on air during commentary, only for Vince McMahon to admonish him. When Foley explained to Vince that he was to blame by ribbing Al so much, Vince said he didn't mind anything that Foley did and said the problem was that Snow did it on the air. While Foley said he would back off a little as to not actually hurt Al's feelings, he said he felt a little giddy that the boss basically gave him full permission to keep on ribbing Al if he felt like it.
Crossed with a kind of accidental moment of Heartwarming: Once wrote a blog where he claimed that Stacy Keibler had told him that his jokes about Test actually led to them becoming a couple off-screen because she actually felt sad for him.
In one shoot, Foley describes his "lowest moment."
In TNA, Eric Bischoff was about to shave Foley's head. Until Foley stopped him, slipped on Mr. Socko and hit him with a mandible claw. While Bischoff was KO'd, Foley turned the tables by shaving Bischoff. Hilarity Ensues.
In his book Have A Nice Day, Foley related a moment in WCW when he was booked to battle Ron Simmons for the WCW World Heavyweight Title. Despite being booked to lose, obviously, Foley teased that they might see a new World Champion at the end of the night. Ole Anderson put it best: "Mick, I don't care if that fat bastard has a heart attack in the middle of the ring, you will pull him on top of you."
As part of the build to the Mankind-HHH match at Royal Rumble 2000, DX had been, of course, making Mick look bad by having Dennis "Mideon" Knight running around as "Fake Mankind." On the January 10thRaw, Mankind tied up Mideon to a chair in a dressing room. He then approached Tori (Terri Poch) in the hallway and mentioned how he was a good kisser and that there were "seventeen other things" he'd like to do to her "sweaty, heaving, voluptuous breasts" and slapped her on her ass. He told her to meet him in Room #3 and to "Bring a friend, there's plenty of Mankind to go around! Yeah!" Tori is speechless and, after the commercial break, she is MAD and power walking down the hall with KANE by her side. Kane attacked Mideon, demolished him, threw him around and chased him up a stairwell, with Jim Ross saying, "Mick Foley's a genius!" In Foley Is Good, he wrote how he was going to be able to say these things to Tori and slap her and he wouldn't get in trouble with his wife Colette.
