Maybe this one isn't completely bizarre, but Adele's rider certainly is one-of-a-kind and thoughtful. The British singer requests that all guests who are given complimentary tickets give a donation to charity -- to the tune of $20.The collected funds are forwarded to Sands, a U.K.-based charity known for “supporting anyone affected by the death of a baby and promoting research to reduce the loss of babies’ lives.” How sweet!
