Here's a new game:
Wait until a fart is brewed, then pretend to take a photo of someone - but with the camera set to video mode. Mid "fauxto" bring the camera down to the arse and release the fart (it is important for the camera to be close to the emitter, as it records the sound with more clarity and impact). Immediately return the camera's attention to the subject in order to capture their reaction to the raspberry.
In this case the reaction was pretty muted as we were at my sister's and everyone was asleep, but I just *know* there are some great ones waiting to be caught. Who will fall victim to the next fartograph? In many ways, I hope it's me. I think farts are funny.
