If you’re not one of the 8.5 million or so Americans who have seen Baby Micah laughing at ripping paper, then you should definitely see it now.

What started as a quick video of Marcus McArthur ripping up his rejection letter (and then garnering some big laughs from the little Micah ) has now exploded into an internet sensation. With some help from Alyssa Milano’s tweets, I guess anything is possible. Marcus shared his only regret with St. Louis Today, “If I knew this was going to happen, I wouldn’t have had him in his pink outfit.”

Now the big question of the day is which did Micah find funny: was it the ripping paper or the irony of ripping a rejection letter? Matt Lauer from the Today Show finds out if just any paper can make Micah laugh.
