Avi Greengart is a real American hebrew. He got his wife to crochet this badass yarmulke with all his favorite gadgets, including an iPod, a Treo, and a PSP. It even has Bluetooth, although it doesn't work, as Avi explains:
The Bluetooth functionality of my yarmulka is non-functional. Some have speculated that this is because my wireless carrier crippled the Bluetooth support and will not allow the yarmulka to support OBEX or DUN profiles.
Lots of people don't realize Yahweh makes a big portion of Heaven's revenue selling "Dreidel Dreidel Drediel" ringtones.
