Ask them to marry you and then selct the cheapest, oldest possible invitations. Make sure your soon to be ex sends out the invitations, including licking the by now toxic glue strips. Go home to find them brown bread on the rug. 'No comment' every question the scuffers throw at you. Free as a bird and no embarrassing encounters to mar your social life. To be on the safe side destroy this thread. And don't worry about the ethics of the thing, if it's good enough for George Costanza...
