# "I have always taken you with a grain of salt. On your birthday when you asked me
# to do a striptease to the theme from Mighty Mouse, I said okay. When we were at
# that hotel on prom night and you asked me to sleep underneath the bed in case
# your mother burst in, I did it. And even when we were at my Grandmother's funeral
# and you told most of my relatives that you could see her nipples through her
# burial dress, I let it slide, but if you think I'm gonna suffer anymore of your
# shit with a smile now that we've broken up, you're in for a big fucking
# disappointment."  - Rene, Mallrats
