"Sorry, but that's the rules"

Those are liberal rules. The only thing you changed was the fact that these "rules" are your fantasies about your mamma.

Here's the original reading from the liberal handbook of sexual perversions:

you must phuck the dead mommies after they stop flopping while they are still warm and before rigor mortis sets in. You won't impress your liberal friends and earn your mamma killer merit badge unless you get a little mamma blood on your dick.
