(My sister is a great cook, but very ditzy. She has just put the turkey in the oven for Thanksgiving. My mother is a great prankster.)
Mom: *to my sister* “Honey, we’re out of chicken broth. Can you run to the store and
grab some more?”
Sister: “Sure, mom.”
(She leaves.)
Mom: *opening the oven and taking the turkey out* “Open the fridge, hun.”
Me: *opening the fridge* “Why? What are you doing?”
Mom: “Just check the crisper drawer.”
Me: *pulls out a Cornish game hen* “What?”
Mom: “Here, season it.”
(I do as she says. My mother slides it inside the turkey’s cavity, and sticks it back in the oven. I start to get a sense of what she’s doing. Later, my sister is carving the turkey before the extended family.)
Sister: “Ohmigod!” *tugs out the Cornish game hen*
Mom: “You’ve cooked a pregnant turkey!”
Sister: “Ohmigod!” *bursts out sobbing*
(It took us a half hour to convince her that turkeys lay eggs!)
