nonsequitur

My normally-coherent friend Cheryl, uttered a classic nonsequitur today:

"My arms really ache. I think I've got irritable bowel syndrome."

{pause}

(during which time I'm wondering how those two are linked and coming up with a very disturbing, yet plausible, possible reason)

"Er, I mean repetitive strain injury. Ha ha ha."

Fair play, the girl can laugh at herself.
