If it were allowed, how would you try to put off another player on the golf course?
We already saw Martin Kaymer try to put off players during the Hero Challenge by standing over Matthew Fitzpatrick's putts, but in this video - there are a lot more props involved.
In this hilarious video, European Tour professionals Andy Sullivan, Thorbjorn Olesen, Paul Waring and Nicolas Colsaerts play a two-on-two foursomes match - with a twist.
With everything from water balloons and shuttlecocks to leaf blowers and megaphones, the players do their best to put off their opponents, with some hilarious but mixed results.
