Funny cheque

This is the best cheque I have ever received. I got $5 per draw for two 50 mL blood samples = $10 - okay so that's just a good lunch - but it says CD1d T cells on it!!!

(It was for a lab that studies natural killer T (NKT) cells and autoimmunity. The reason they need such big volumes of human blood is because NKTs are rare.)
