Roger Waters is playing Pokemon Blue on a Game Boy... A younger guy gets up the nerve to walk up to him and say ""That pretty cool. Were you always a Pokemon fan?"" ""Oh yeah, the Game Boy was just the coolest thing when it came out"" he replies. ""I remember, yeah, it really was. You know, it's funny, I played mine so much I used to have a name for it. It was like a friend you could always turn to, you know?"" The young man realizes that he's saying stupid things in front of his idol Roger Waters and looks away in embarrassment. ""Oh definitely. I had a name for mine too. Who didn't? What was yours? The young man sheepishly responds,""Well, I'm not gonna lie mine was named Mycroft, you know, like Shelock Holmes's bother."" He looks a away for a second but then returns, ""What was yours named?"" Roger looks at him with a knowing glint in his eye ""I'll tell you the name of the Game Boy. I called it 'Riding the Gravy Train'."" (This might be an obscure joke, I don't know. Be gentle.)
