Line from Jonathan Larson's RENT (1996 Tony Award and Pulitzer winner). Sung by Mimi Marquez (a nightclub dancer with a smack problem, as well as AIDS), to Roger Davis (a classic starving musician who's HIV+ and looking to write one last song before the lights go out).

The actual line comes from the song "I should tell you" and goes thusly:
Roger:"I've been trying, I'm not lying, no one's perfect, I've got baggage-"
Mimi:Life's too short, babe, time is flying, I'm looking for baggage that goes with mine."

In the Original Cast Recording album, Mimi and Roger are voiced by Daphne Rubin-Vega and Adam Pascal, respectively.
