Old Spice's collaborations with Terry Crews continue, and in the latest, an online video game called Muscle Surprise, you can "explore" the various muscles in Crews' body to see more zany video clips and animations.

Click on each muscle in turn to see an animated tiger try to find a home there, watch popcorn pour out of his pecs and see Crews play various characters including his Mom, Dad and a doctor. You'll get a different sequence of events depending on how you click. It's pointless, ridiculous fun.
