Sorry to go all text-speak on you but, since we're in the medium, I figured it appropriate.
For those of you who may not know - LMAO = Laughing My Ass Off and that is exactly what Ben is doing below.
Prompted by the always hilarious mom-and-the-stuffed-animal routine, Big Ben provides big laughs. As you know laughter is infectious so we also started to laugh. And each time we play it, we get more and more cheerful. We hope that this spreads a laugh or two your way as well.
