I Hope Your Firstborn Is A Cripple
Disproportionate retort to a perfectly reasonable statement. For example:

"Hey Andrea, have you got a red pen I can borrow?"
"No, sorry."
"Well then, I hope your firstborn is a cripple."

If anyone from Killy High has since given birth to a crippled child, I accept no responsibility for it.
