I'm not advocating that you do this, but I'm pretty sure that my son got the most unique hospital gift that I've heard of. He was in the hospital on his 21st birthday. Not scheduled, in fact he was in intensive care following emergency surgery due to a life threatening complication from Crohn's Disease. Not at home, but in a strange hospital 7 hours from home. With a scared mom.
One of his friends decided to bring him what she had already planned to give him. A very VERY large brandy snifter filled to the brim with airline sized bottles of various "spirits". We kept it on his nightstand, and all the doctors and nurses laughed about it, asking him how his spirits were holding up each day. Obviously, we weren't utilizing the contents, but it made him glad that at least his birthday wasn't overlooked.
