An exclamation or statement expressing the sentiment that one should never become so grown-up that one loses the ability to be childish.

Longer expressions that mean the same thing:
"Never get so battle-fatigued that you can't enjoy your shore-leave."
"Never work so hard to provide for your kids that you lose the ability to play with them."

Origin: In the children's book Wayside School is Falling Down, a boy named Calvin gets a tattoo of a potato on his ankle because "he likes potatoes." This expression is a reminder to always keep some of that simple innocence in your heart.
Barney: "Wanna go play laser tag?"
Ted: "Why on earth would I want to do that?"
Barney: "Potato!"

Guy: "Want to come over?"
Girl: "What would we be doing?"
Guy: "I'll give you a hint: it involves pillows and sheets. ;)"
Girl: "OMG we're gonna build a fort?!"
Guy: "..."
Girl: "Potato!"
