My favorite response when someone tries to tell me a knock-knock joke

Doors open

Also:
"Jesus, the door's open. No need to knock."
"OH SHIT IT'S THE COPS HIDE EVERYBODY"
"Use the goddamn doorbell, were you raised by wolves!?!?"
"No one's home. Go away."
*must be said in a high voice* "Michael, hide! My husband's home!"

"Knock knock."
"Go away."

Mishaaaaa *-*
