We all know of the hilarity caused by footballs to the groin. But a golf ball?

Tyler Seguin of the Dallas Stars let a guy smack a golf ball off a tee that was resting on his groin during The Fourth Period charity classic in Nobleton, Ont.

The way the video is displayed on Seguin's Instagram page, you actually have to click on his crotch to make it play. 

In case you missed it, at the end of that video, Seguin says, "It tickled."

The Fourth Period charity golf tournament benefits CAMH, helping those with mental health issues. Seguin is a big supporter of the event.

Judging from this video, golf balls off the groin may be more regular than you think (scroll ahead to the 2:05 mark).

Perhaps next year to up the ante, Seguin will let someone take a slap shot while resting the puck on his groin. Or not. There are very few insurance plans that cover slap shots off the groin these days.
