An eminent psychologist was called to testify in court. A severe, no-nonsense professional, she sat down in the witness chair unaware that its rear legs were set precariously on the back of the raised platform.

"Will you state your name?" asked the district attorney.

Tilting back in her chair, she opened her mouth to answer, when she was catapulted head-over-heels backward and landed in a stack of exhibits and recording equipment.

Everyone watched in stunned silence as she extricated herself, rearranged her disheveled dress and hair, and was reseated on the witness stand. The glare she directed at onlookers dared anyone to so much as smirk.

"Well, doctor," continued the district attorney without changing expression, "we could start with an easier question."
