"I vant to dreenk your blud!"
Although I have a feeling he does say this. He looks a bit vampirish.

How else would he stay so young and virile?

Also:
"I'm sorry"

"Nice to meet you."

"We need don't need any more money. We're giving it all to the poor."
"Feel free to use condoms and prevent AIDS becoming even more of a problem."

"how's the weather?"
"Ah, batman, we meet again."
"Oh god..."
"THE VOICES, MAKE THEM STOP!"

"I just found out about this stuff called science, and we're wrong about a lot of things."

"Note to self, pick up more count chocula at the store."

"It's a pleasure to meet you, Mr Hawking."

"Yo struggling African communities, how's that AIDS going? Also don't ever ever use condoms because they're conducive to sin."

....wait.

Let's keep the religion bashing to a minimum, please.

"Can I have your first born son?"

I feel like I'm allowed to bash my own religion, thank you very much.

Yeah, well that's fine, but some other people might be offended. (NOTE: I am not catholic.)

"PEW PEW"

"Pope powers activate!"

"Wave your hands in the air like you just don't care"

"Whats that? some ones introuble, Super pope away!" [flys away in dramatic mannor]

"Whilst you're at it, can you grab me a copy of 'New Scientist'?"

"I'm walkin' on sunshine~!"
Well, he might say that, but he wouldn't sing it well like I'm imagining it in my head.

"Take this bullet-proof glass off of the pope-mobile. I trust that god will protect me from bullets.
