He's been Cactus Jack, Mankind and even Saint Mick ... but pro wrestling legend Mick Foley says his favorite WWE alter ego isn't any of those guys -- it's someone way more corporate!
"I'm gonna go with 'Corporate Dude Love," Foley tells TMZ Sports ... "Where I got to dance with Mr. McMahon!" That's the first time I've ever given that answer!"
Don't get it twisted ... Foley says he LOVED being Mankind -- especially when he teamed up with a "little known entity named Dwayne 'The Rock' Johnson.
