Imaginary photographic device which confuses at one end and amuses at the other.
Origins: Last year, staff at my office got to meet all the Australian Idol contestants at a drinkies do in our boardroom. I was chatting to my mate Olivia when one of the more aesthetically pleasing Idols walked past, and she mentioned she wanted a photo with him, primarily so she could nestle into his barely post-pubescent armpit. Unfortunately Olivia didn't have a camera. I suggested that she should go up to him anyway, pose with him, and I would just mime taking a photo of him on an imaginary, invisible camera.
She wimped out.
Later in the evening, Olivia and I went out, and eventually she found herself being chatted up by an outrageously good-looking, stunningly stupid man.
She tapped me on the shoulder and, smirking, said "Hey Jo - do you mind taking our picture?"
"Sure!" I replied, going through the contents of my bag to find my invisible camera.
Having found it, I raised it to my face and mimed pressing the shutter button.
The guy barely blinked.
"Wait," said Olivia. "The flash didn't go off. Take another one".
Anyway, here's the photo:
Damn. I cut their heads off.
