Your mother dresses you funny

Not really an insult, but I find this an amusing callout when someone interrupts you in a conversation:

"Sorry, that the middle of my sentence interrupted the beginning of yours."

Your birth certificate is a letter of apology from the condom factory.

You bastard, its only a dlc.

I once owned a dog that was smarter than you.
