Tuesday dinner

Mom: Now I know why you've gotten so fat! You spend all day on the internet.
A.: Not really.
Dad: She's gotten fat because she takes after me, and I've gotten fat.
Mom: You've gotten fat because you're old. As my mother used to say, "eto nye ot kotlyet, no ot lyet." [It's not from burgers, but from burgers. It rhymes.]
