[Overheard] - "How do I get balls?"

Officemate:  So I got everything all set for the event.  Computers, powerstrips, food.  Only thing I forgot was chairs! [smacking forehead]
Me:  Why don’t you use these instead? [pointing to one of the inflatable balls we have in our office for sitting on]
Officemate: [looking intrigued, yet uncertain]  Hmm!  How do I get balls?!
Me:  [incredulous pause, then uncontrolled laughter]

Luckily my officemates have a good sense of humor :-D
