John Krasinski takes on Stephen Colbert in a brutally tense arm wrestle

“Warn our affiliates we might be going long.”

These are the words of pumped up Late Show Super Bowl special host Stephen Colbert as he rips off his jacket so aggressively that his mic makes an audible thump, in preparation for an arm wrestle with guest John Krasinski.

There’s plenty of fighting talk from Colbert as he slaps Krasinski’s bicep and informs him he’s “gone soft”, but ultimately the IF director/writer emerges the clear victor.
