Two friends argue over who is going to get to eat the last slice of pizza. Battle lines are drawn, the big guns (neither of which are guns) come out, and chaos ensues.
One draws his light saber, and attacks his friend. The friend then does the same, and the two embark on an epic lightsaber battle George Lucas would have been proud to direct.
Then the Portal Gun somehow makes it into the mix, which livens things up no end until one of the guys gets caught in an infinite loop.
Still, an astoundingly good aim means he still wins out in the end… except it means he’ll carry on falling until he dies of thirst.
