LITTLE ROCK - The Arkansas Teacher Retirement System doesn't encourage its members to call phone sex lines. But that changed this week, thanks to a typo.

The retirement system sent out letters to retirees and active teachers explaining how to name beneficiaries in the event of their death, said David Malone, the association's executive director.

Some of the pages in the letter listed the correct toll-free number associated with the program, he said. But one page listed a toll-free number that brought callers to a recording of a seductive woman's voice.

"Hi, baby! Do you want to massage my feet or suck my toes?" the woman asks. She goes on to explain that "foot fetish fun is only 69 cents per minute" and offers another number to call "for all the hot, one-on-one triple-X toe talk you can handle."

"We've had a few calls about it," Malone said. "Most everybody's been pretty good natured."

The letter with the wrong telephone number went out to about 50,000 system members. Another 50,000 will get letters with only the correct number.
