The fine art of cheating. (Found on another site.) Here are five tried and trusted ways of cheating. When you just need that little bit of extra help...
1.
Unplugged. Pull out an opponents controller at crucial moments by slightly dislodging the cord from the port. Make it look like it was an accident because he was pulling on it to hard.
2.
Rig drinks. Tampering with opponents drinks will put them off their game. Some tobasco in their diet coke should do the trick...
3.
Nudge, nudge. Elbowing is an extremely dirty tactic, but extremely effective. Just blame it on that muscle spasm...
4.
Who you gonna call? Set your mobile to their number and then make the phone go off at a critical part of the game. Works every time.
5.
Trash talk. Plenty of banter never goes amiss. Aside from insulting their family, try game specific terms of abuse e.g. soccer. Blame the computer for a goal that the computer accidently did, even though you know that it was your own fault.
