Seth MacFarlane absolutely DESTROYED Ryan Lochte during this weekend's "Saturday Night Live" ... and while the swimming star says he hasn't had a chance to see it yet, he certainly didn't seem too pleased about it.
MacFarlane appeared as Lochte during the "Weekend Update" sketch to do a preview of the new shows on television. Seth portrayed Lochte as an ABSOLUTE IDIOT ... referring to the new show "Go On" as "Goon" (he didn't realize it was two words) and at one point randomly saying, "It feels so weird to be dry."
Lochte told us over the weekend he hasn't checked it out yet -- but judging by his tone, he probably heard how brutal it was.
If, like Lochte, you haven't seen it either ... check it out below. We give it six swims.
