Jumping into a pool of frozen water wearing nothing but a Speedo-Hot Pants hybrid would demand of any reasonable primate at least a fleeting expectation of pain.

This German daredevil, however, seems to take to the task without so much as a consideration for the spectrum of injuries he's likely to sustain.

That's probably what makes his subsequent exclamations of "mein Arsch" all the more amusing.

(Also, a notable mention goes to the top YouTube comment: "He should put some ice on that.")
