That's awesome. I loved how he sat like he was handcuffed on the floor.

He's just an amazing person, and amazing actor. Everything I ever hear about him off-screen just makes me love Jensen more and more.

Have you read the Sam and Ben spn/da crossover? It's under the Tom Sawyer tag if you're interested.
There's also a quick jensen-plays-piano fic at the rpsgen tag.
