New York City has started giving mock Bluetooth cellphone headsets to its homeless people. The effort is intended to remove some of the social stigma of these people due to their self conversations.

Comedian/actor Billy Crystal spends over $4000 a year on prepaid cellular phones that he uses to make prank phone calls. He claims that it keeps his "comic chops" fresh. He even tried to claim it as a business expense on his tax return until his accountant talked him out of it.

Actor Adam Sandler used to scream involuntarily every time his cell phone rang. This continued until his personal assistant had the bright idea of changing his cell phone ringtone to the sound of Sandler screaming.
