A loooong time ago when my younger son was 2 or 3 or so he has getting cranky about some silly thing so I told him to cool his jets. Man did that set him off! He immediately started crying, stamping his feet and screamed "I DON"T WANNA COOL MY JETS!!!!! WAAAAAAAAAAAAAAAA!!!!!!!"
And no, I didn't T him up for USC, I just hugged him until he calmed down. Miraculously he's yet to hold up a gas station or become an ax murderer. As far as I know.
Thanks for jarring that memory loose for me!
