"On behalf of the entire NBA and half of the rappers on the Billboard charts, I want to thank you for giving your daughters their daddy issues!"
That's NBA superstar Blake Griffin giving it to Caitlyn Jenner at the Comedy Central "Roast of Alec Baldwin" -- proving absolutely nothing is off limits ... and it's all hilarious!
Blake and Caitlyn were on the dais for the show (which airs Sept. 15) -- and it's customary for roasters to go after each other in addition to burning the guest of honor.
