A Killer!!

[RATTER15]

The wife came back from buying her costume for a fancy dress party earlier.
"Stay there baby" she said to me, "while I nip upstairs and put it on to show you."
She came back down, opened the living room door and stood before me.
"Wow honey, that's a winning costume you've got there." I told her. "That's the most convincing killer whale outfit I've ever seen."
"I'm a nun, you pudding"
she screamed.....
