They call him "The Giant."
And to be fair, you can't be giant without having a giant ass. It would make perfect sense then, to make sure anyone who stands seven feet tall and weighs 500 pounds, has a chair big enough to accommodate them. And if they choose not to sit in it, well, they can always use it to clown a ginger in front of a live audience.
That's exactly what happened when The Big Show beat Sheamus to retain his World Heavyweight Championship in a "Chairs Match" (you're not getting him on a ladder) at the Tables, Ladders & Chairs (TLC) pay-per-view (PPV) back on December 16, 2012, at the Barclays Center in Brooklyn, New York
See for yourself (skip to the 17:15 mark):
JBL: No! No! No!
Michael Cole: That's like getting hit with a billboard!
Big Show has a big chair, so maybe when John Cena finishes unifying the titles, we can get him a big belt?
