Robin: You have to go home and get to bed.
Barney: Oh, Robin, my simple friend from the untamed north, let me tell you about a little thing I like to call mind over body. You see, whenever I start feeling sick, I just stop being sick and be awesome instead. True story. Yeah, in two minutes, I'm going to pound a sixer of Red Bull, hop in a cab, play a couple of hours of laser tag, maybe get a spray-on tan. It's gonna be legen... Wait for it... [Barney falls asleep]
