Richard Sherman is at it again.

This time, though, he's running his mouth about cancer. The Seattle Seahawks' star cornerback who made headlines during last year's playoffs for a post-game rant recently took some time to make fun of himself.

Parodying his rant, Sherman worked in an advertisement for the Swedish Cancer Institute, one of the top care givers in the Seattle area.
