Use your...

Picked up a N.E.R.D x H&M collabo shirt last weekend. I guess 25% of the profit goes to AIDS foundation. Okay let do the math now...$24 for shirt...$12 or $13 profit..so $4 will go to the foundation. So w/ 10,000 shirts sold (highly doubtful)...then it'll donate about $40,000. Which is probably enough for about 10 experiments to test that "new drug."
