Crossover Conversations Meme

I need a kickstart, SO:

Give me two characters from different fandoms you know I’m familiar with, and I’ll give you a dialogue happening between the two of them. Without justifying how the crossover would work, how their worlds clashed, or how they could even meet each other. Just a silly crossover conversation with no backstory, for fun.

For your convenience, a PROBABLY INCOMPLETE list of fandoms. ETA: I've italicized fandoms that have yet to get any love. Don't let that stop you from picking people from the loved-on fandoms. ESPECIALLY THE JONAI, they're like INSTA-CRACK with 90% of these others.

RPF:
Jonas Brothers, Bon Jovi, Flogging Molly, Black Rebel Motorcycle Club, Edguy, Iron Maiden, Def Leppard, Zefron, Al Gore (dear everyone who understands why: I miss you, comment and post more). I'm sure you can come up with more I've written/fanned.

FPF:
Torchwood, Merlin, Leverage, Mad Men, JONAS, High School Musical, Big Love, Lost, probably some others idk. Basically anything I've ever watched is suitable for meme purposes.

GO BIG/CRACKY OR GO HOME, PEOPLE. Request as many as you want.
