@kaia I think the "coolest" things I got were for my son. He's had the same hooded blanket since he was a toddler so I got him a customized adult sized one that was Minecraft Themed. Also got him some Minecraft Themed D&D Dice.
I got @Johncdvorak 's wife's Too Many Eggs book for a friend which is partially an inside joke and partially because he likes esoteric things.
You?
