(Video: Kal Penn ad for Obama livestream)

Hey, stoner humor! The Obama team released this comic video late Monday advertising Kal Penn’s role at the convention — hosting livestream coverage at the campaign’s own Web site Thursday — with a cameo from his “Harold & Kumar” co-star John Cho. Party on! No giggles from weed legalization proponents, though. Morgan Fox of the Marijuana Policy Project griped to Talking Points Memo that “the fact Obama uses these characters to joke about this issue while on the other hand continuing to arrest people he’s appealing to is really disingenuous.”
