Mm' sorry for callin' you trash panda, but for real, dude--I was not the one laughing. Maybe... [A puzzled frown.] It's probably the building we're in. Sometimes weird stuff happens in them. Or there's ghosts or whatever passes as ghosts here.

[As a peace offering, he reaches in his pack and pulls out his precious Zune, still losing battery every time he risked playing a song.]

Here. Turn the music up and you won't hear laughing. Might help.
