My grandmother made me memorize "If I only had a brain" when I was young and I still sing it from time to time.  She said remembering it will keep me from taking things or myself too seriously.

Dancing!

I love anything from the Backstreet Boys (go ahead and laugh, but they've got some real talent)

Kelly Clarkson

Pink (one awesome woman here! -- she got me hooked after her "stupid girls" song was released)

Lady Gaga

and online:
Karmin (she has an awesome hair tutorial in case the ladies are interested in how to get rockstar curls)
Walk off the Earth

The guy in the video (Sean Stephenson) is not a dwarf in the true sense. He is short, so he meets the criteria that way but really he has Osteogenesis Imperfecta (OI), also known as Brittle Bones. His particular flavor of OI makes it so his bones are unable to support his body weight, forcing him in a wheelchair. Some people very close to me have it, and are reasonably healthy. Kid President has it too. It's why he's short. (you can see kid president in various casts in his videos, but you don't hear him talking about it much.)

It's so great to see two people with such a rare condition living such positive lives. We all should realize how many "lotteries" we won just by being born at all, in America, with the advantages we have over others. Many many lotteries were won and we need to see it, celebrate it, and DANCE  

Allison, THANK YOU for this great reminder to enjoy life and dance

Ned's Atomic Dustbin......  Always brings me back to a simpler time of being in school in Boston.
