Is this what you'd call going "viral"? Youtube says this video was published on April 20 (and there's no pot smoking in it!), and that it currently has over 2.7 MILLION views...and 23,000+ comments.
UPDATE: Well, duh...Mr. Can't Read. That was 04/20/2012. No wonder there was Muh-Muh-Muh-Millions of hits. But this one is newer. And there's also one in tribute to Milton Friedman! Go.
I'd say that's getting your viral on. H/T to Free Republic.
