Snoop Dogg opened up his GGN show by recalling to Jimmy Kimmel the time he sparked one up in a White House bathroom. He said that one of the guards asked him if he was going "number one or number two," and he explained that he likes to light up something to "set the aroma right." 

The "Drop It Like It's Hot" rapper explained that the guard told him to burn a napkin, but he sneakily lit up some herb in the bathroom instead.
