Hilarious ad for nature call golf club

What do you do when nature calls on the golf course?

Head back to the clubhouse? Look for a large tree or some bush cover?

Well not any more, thanks to the Uro Club.

A US company has come up with what could be the most vital tool in a golfer's bag after manufacturing a hollowed out iron designed for, you guessed it, answering nature's call.

A 2010 TV ad featuring the Uro Club has gone viral with hilarious footage of golfers peeing into their club proving an online sensation.

One shot, in particular, takes the cake with an elderly player simply resting a towel over his club while he relieves himself in the middle of a fairway.

Of course the club is not for everyone, particularly female players, but it sure beats a hasty retreat back to the clubhouse in the midst of a round.

And if nothing else the footage of test pilots showing how handy the club can be is more than a wee bit funny.
