Nearly one-fourth of workers (23 percent) say that their bosses have asked them to help out with assignments that fall outside of their job descriptions, according to a recent CareerBuilder survey of about 3,600 U.S. workers across various industries and company sizes.

Here are few of the most outlandish requests employees say they have received from their bosses:

• go online and post false good comments about him

• come up with a science fair project for her daughter

• lend him $400 for a down payment on a car

• remove her stitches

• scour an abandoned office building for furniture and supplies

• clip her dog's nails

• help plan her wedding.

Despite the unusual requests, most workers report liking their bosses, and think their bosses perform their jobs well. When asked to grade their boss's performance, the majority gave an above-average report of A (26 percent) or B (40 percent). Meanwhile, nearly one-third of bosses received a just-passing grade, with 20 percent earning a C and 9 percent a D. Sadly, 6 percent of workers gave their bosses a failing grade.
