I'm pretty sure it was linked here - it was four babies lying on their mom and cracking up at something dad was doing. Entertained me for a week or two. Anyway, turns out the babies are identical quadruplets (now 6 years old) and the video just won $250K on America's Funniest Home Videos. I tried to find the video again, but my searching skills suck.
Have no fear, Alice is here.
