T-Rex: Some guy told me that doing a task would be "easy as pie"! And it's like...

T-Rex: "Uh, wow, BRAG much??"

T-Rex: Because I've tried making pie and it's HARD. You want a crust that's flaky and moist but not wet on the bottom or burnt? Ho ho, hope you know what you're doing because it's certainly not easy!!

Utahraptor: Maybe the expression is shortened?
T-Rex: How so?

Utahraptor: Like MAYBE the expression was originally "easy as [reheating a pre-made] pie [that you got at the store]", or "easy as [eating an already-cooked portion of delicious] pie [someone else made]".
T-Rex: Oh! Those ARE easy.
T-Rex: Okay, I retract my previous complaints!

T-Rex: Yep! You gotta fill the days somehow, and THIS year I decided to be mad about expressions, but only for a little while!
T-Rex: And now: back to bed
