Your Mother is so stupid she drives around in a wheel chair thinking they'll let her park it in the handicap spot!
yo mama so stupid she thought she could play the death waltz! (look it up on youtube! its actually a really cool song!)
Your Mother is such an imbecile that she does not know the difference between her right hand and left hand.
