I love bobbleheads and am dismayed that I don't own more. In fact, the only one I really own is a Jerry Stackhouse bobblehead from 2004, and it broke. So it's only fair that I point you in the direction of this John Carlson bobblehead (picture below the jump).
You can acquire this amazing Carlson bobblehead simply by donating blood at the Capitals and Inova Summer 2010 Blood Drive in Dulles, Virginia on July 24. Good cause + awesome bobblehead? Seems like a pretty good deal to me.
