Most fourth-grade teachers use their spare time on the job to prepare lesson plans, work one-on-one with students, even put up new colorful bulletin boards in their classrooms.

But Amber Carter, a 35-year-old teacher in Bellefontaine, Ohio, allegedly arranged afternoon prostitution gigs at an area motel. Authorities say Carter even skipped class at least once after using a school computer to arrange one of her "appointments," which actually turned out to be a police sting operation. It turns out, Carter allegedly was posting cash-for-sex ads on the Web site Craigslist.

Needless to say, Carter was placed on administrative leave from her job. She has worked in the district for 13 years, first as a kindergarten teacher.

"It’s really a shock," Bellefontaine City Schools Superintendent Larry Anderson told AP. "She’s never been involved with any disciplinary issues or anything else. She’s done a very good job."

Maybe she was desperate in this bad economy? You know what they say about desperate times…
