Rasmus doesn't play pranks at all, in fact he hates pranks. His disdain for pranks is known so well by his teammates that he escapes all of the typical practical jokes - either given a heads up in advance or they'll design the pranks in such a way that they couldn't fall within his sphere of day to day life. It all started when he was a kid - his friend put a whoopie cushion under his seat. He sat down, and everyone laughed and thought that he had farted, but he had not actually passed wind. Quite the embarrassing moment for young Rasmus. Then a week later, it happened again to him. He vowed at that moment, that he would never pull a prank on anyone, nor would he allow pranks to be pulled upon him lest someone have to go through the 3 seconds of laughter and then everyone else forgetting that it had even happened by the end of the day - he wouldn't wish that upon his worst enemy.
