I was just drumming/tapping/beating my register & he starts to match me & I look at him & he smiles & goes
“I just made that up”
“Oh did you?”
“Yeah, you can buy it on iTunes”
*laughs* at the same time we both joked how it was one of the $1.99 songs - cause thats how popular & awesome it is.

That sparked an interesting conversation about music & itunes & pandora & I introduced him to Last F.M.
