Bob will enjoy the Richard Thompson reference (my ringtone is Whole Lotta Love - any song in the same key with the same kind of riff gets me):
SIX minutes 39 seconds into the Richard Thompson song "Calvary Cross," Mike Pelusi, a music reviewer in Philadelphia, will almost invariably check his cellphone. Minka Wiltz, an actress in Atlanta, has tried to answer her phone to the thrrrrup, thrrrrup, thrrrrup of a truck bouncing down a pothole-pocked street. Others say they thought they heard phones ring while taking a shower, using a blow-dryer or watching commercials. What they are hearing is a barely discernable sound — perhaps chimes, a faint trill or an electronic bleat — that they mistake for the ringtone of their cellphone, which isn't ringing. This audio illusion — called phantom phone rings or, more whimsically, ringxiety or fauxcellarm — has emerged recently as an Internet discussion topic and has become a new reason for people to either bemoan the techno-saturation of modern life or question their sanity.
