10:15 AM PT -- 1/29 Wee Man was all smiles after getting body slammed through the dinner table ... laughing and roughhousing with Johnny Knoxville.
We obtained more video showing the aftermath of Brock's wrestling move on Wee Man ... and it's clear everyone thought it was hilarious, even Wee Man.
Knoxville daps up Brock and then hilariously explains the incident to a couple of nearby guests ... and it sounds like he was the mastermind of it all.
File this under warming up for Bobby Lashley ... 'cause on the eve of the Royal Rumble, WWE SuperstarBrock Lesnarjust BODY SLAMMED Wee Man through a table -- at dinner!!
TMZ Sports obtained video from Lesnar's dinner table at a restaurant in St. Louis when the 6'3", 285-ish lb. behemoth picked up the Jackass star -- as Johnny Knoxville (who's in the RR) watched -- and sent him crashing through the wood table, breaking glass (and possibly Wee Man's back?).
The clip's great ... the future WWE HOF'er casually picks him up, holds him, and then ... boom!
Of course, Brock -- the WWE Champion -- is in Missouri for the Royal Rumble ... where he's taking on the challenger,Lashley, Saturday night at The Dome at America's Center.
Lesnar and Lashley isn't the only big time matchup. Roman Reignsis wrestling Seth Rollins, Becky Lynch vs. Doudrop is also going down ... and there's a bunch of other Superstars scheduled to be in the house.
As far as Wee Man -- aka Jason Acuna -- the good news is we're told he's okay! Maybe just a bit sore ... 😬😬😬
