Reminds me of the Simpsons:Reminds me to see if I can get bumped up that vaccine list because I donate platelets and plasma. They test you for antibodies, I haven't caught it yet. They can farm me like a horseshoe crab once I got that good plasma.
Smithers: "Uh, sir - I believe that job was informally promised to me."
Burns: "Oh, Smithers - I would've said anything in order to get your stem cells."
Or something like that...
