Angel and Supernatural

There's Jeffrey Dean Morgan in Angel 3x12 Provider as a Sam Ryan. *squeee*
I'm the only one who didn't know that until now, right? *lol*

Angel:	These vampires killed your friend.
SAM:	Look. I'm sorry about what I did. I needed help. I didn't know what else to do.
Angel:	So you lied to me.
SAM:	I'm sorry.
SAM:	I'm sorry I lied to you. I shouldn't have.
Angel:	No. You did the wrong thing. But your heart was in the right place. Your motives were noble.
SAM:	Thank you.
ANGEL:	It's not as though I haven't been accused of nobility myself once or twice.
SAM:	Then you understand.
ANGEL:	Yeah. But being a champion is not all good deeds and happy endings. There's a lot that goes on behind the scenes. People don't seem to consider that.
SAM:	I think - I think we're in real trouble here.
ANGEL:	All right. Maybe we can work something out. You own a car?
SAM:	The bank owns it.
ANGEL:	House?
SAM:	I rent.
ANGEL:	How's your credit. Can you borrow?
SAM:	I'm kind of out of a job. Spent all I had tracking these guys.

Soooo... are there Angel/Supernatural Crossovers? Recs anybody? As long as it's slash and pairs the Winchesters with Angel (or maybe Wesley?) I'll read it.
