The night before ChristmasThe night before christmas,Throughout the enrichment house,Everyone is being tested,Even a mouse...Chell in statis,I'm tired after a long test,I went to my relaxation vaultFor a long restOutside the facilityI heard such a clatterI grabbed my Portal deviceAnd saw what was the matterHe came down the chimneylike a bat of hell'cause The chimney was linedwith repusion gelHe filled our stockingsWith beer and cakeI secretly hopingThe cakes aren't fakeHe sung still aliveAs he flew out of sightShouting i'll be back next yearHave a hell of a nightMerry christmas
