Fourth Doctor: "

You know, the very powerful and the very stupid have one thing in common: they don't alter their views to fit the facts; they alter the facts to fit their views.”

“There’s no point in being grown up if you can’t act a little childish sometimes.”

Tenth Doctor:

“Some people live more in 20 years than others do in 80. It’s not the time that matters, it’s the person.”

“Always take a banana to a party, Rose: bananas are good!”

Eleventh Doctor:

"Nobody important? Blimey, that’s amazing. Do you know, in nine hundred years of time and space I’ve never met anyone who wasn’t important before.”

Elton-
“When you’re a kid, they tell you it’s all… Grow up, get a job, get married, get a house, have a kid, and that’s it. But the truth is, the world is so much stranger than that. It’s so much darker. And so much madder. And so much better.”

Yes the banana quote is relevant; because of reasons.
