'Harold and Kumar' actor Kal Penn speaks at the DNC

Kal Penn, he of "Harold and Kumar" and "House" renown, brought down the latter at the Democratic convention on Tuesday night with a good-humored speech filled with far too many quips for us to transcribe in real time.

He juxtaposed gay marriage and the death of Osama bin Laden in the same sentence. He joked about what the Twitter hashtag on his speech would be (his recommendation: "sexyface"). He recounted a variety of experiences that he said showed him that change under Barack Obama had indeed been change he could believe in.

And Penn, who has volunteered or worked for Obama since 2007, asked for continuing voter engagement -- particularly from the nation's young people, particularly online.

Which manifested itself this way: "I ask all of you young people to join me. You don't even have to put pants on."

Now is that a campaign slogan for the 21st century or what?
