When Tom Brady first signed an endorsement deal with UGG Boots, it wasn't just fans that were skeptical. His own teammates questioned the move too.

Brady's former wide receiver, Wes Welker, revealed in an interview with ESPN that after receiving a pair of boots as part of Brady's annual holiday gift, he couldn't help but mock the quarterback.

So during a walkthrough, Welker showed up in only the boots and a jockstrap.

"‘Is this how you wear them? Tom, is this it? Is this how you wear these?’" Welker recalls asking Brady. "It was probably more of a prank on myself, but we still got a good laugh out of it.”

Welker didn't name the exact game, but if it was around Christmas and if the walkthrough was in New England, it may have been quite cold outside. And while Welker's feet were surely warm, the rest of his body was not.

Here's Welker explaining the prank to ESPN's Stevland Wilson:

Teammates can tease Brady about UGGs all they want, but the future Hall of Famer is laughing all the way to the bank.
