LANE: Wh-what kind of music do you like?
TODD: I don’t know – whatever.
LANE: The band on your shirt.
TODD: Oh. Huh, pretty cool picture.
LANE: You don’t know what’s on your shirt?
TODD: It’s my sister’s.
Fugazi is an American punk rock band formed in 1987, consisting of Ian MacKaye, Guy Picciotto, Joe Lally, and Brendan Canty. Their first album was released in 1990, and their most recent album from Lane’s perspective is End Hits (1998), which looks to be featured on the tee shirt Todd is wearing. The band has been on hiatus since 2003.
Fugazi are famous for not selling or licensing merchandising, creating an enormous market for bootleg tee-shirts. Presumably Lane knows that the shirt Todd is wearing is unofficial, but can’t see the point of discussing it with him.
