The back side of the sign says, "Spare change?"
OK, so we're still not great with communication, huh? He goes on to say, via poster board, that he hasn't seen the object of his former affections since the events of the first movie ... 13 years ago. Which is really weird given that she's married to his best friend. Was she perhaps way less cool with the whole thing than she seemed, blabbing to her husband and leading to a huge falling out between the two friends? Apparently not, because the husband (still upstairs watching a football game, oblivious to the serial killer shit happening down below) makes a fourth-wall-breaking crack about the guy's beard that he's obviously seen. Either he's got laser vision and this is a way cooler movie than we thought, or maybe marker boy just happened to move away immediately after confessing his love but they're still Facebook friends and whatnot. That makes his next reveal even weirder: He's met, fallen in love with, and married Kate Moss -- something he joked about on one of those famed cue cards of old.
"Ah, so you're the one whose name he sobs during sex ... "
Sooooo, he's been keeping that a secret from his best friend's wife -- and by extension, his best friend -- all this time? Why? So he could dramatically reveal it with Sharpie and an iPod? Dude, you still have no idea how humans work, do you? You don't seem to have matured a single bit in over a decade, or even tried to. And you better get on it, or I give your marriage to Kate Moss about the length of a line of blow. Dammit, I was rooting for you.
