And just had someone show me this one...not something that non-classical music lovers would like, but it's hilarious for me. In the symphony you'd see violins playing around pretending their violin was a cello, but nothing like this:

Very Nice.

You're just trying to make cello playing look less nerdy. :-)

You're just trying to get in my pants.

I hope that comment was to ayummy and not me :-)
