This has spurred an Internet meme in which Grylls is depicted drinking his pee for no good reason, but he proved he can take a joke by responding to the meme via Twitter.
In a recent tweet, Grylls says "In honour of all your @replies about pee drinking. am on vacation in LA. Looks like I'll have to drink my own pee!" The tweet is accompanied by a Twitpic (pictured above) of Grylls drinking liquid from a cup with a pained expression on his face.
The tweet itself is now one of the top stories on Reddit, where the meme was first widely distributed (check here for some examples), with more than 2,000 upvotes at the time of this writing.
This is another example of how a positive, timely response to an Internet phenomenon (no matter how cruel these memes sometimes are) through social media can net you an army of fans.
In a similar example, Chuck Norris reacted positively to the phenomenon of "Chuck Norris facts," clever jokes about the invincibility of the legendary actor. It resulted in the release of The Official Chuck Norris Fact Book, a satirical book of jokes penned by Chuck Norris himself.
