You might recall that JR failed to eat the entire 18 oz steak at the Big Texan last year...which there is photographic evidence of.
He reattempted to eat it again this year.
He prepared himself by skipping breakfast and only eating French fries at lunch. His preparations worked and he was able to finish.
I wasn't there to witness the ridiculousness, but Jason said he was acting like he won the Superbowl.
Celebratory big chair pictures were taken.
