You've seen the posters, you've read the reviews and you know exactly what's going to happen but still nothing really prepares you for the moment of truth.
A couple of minutes into David Friend and Simon Morley's genital origami show, the puppeteers whipped off their capes and went full frontal.
The camera zoomed in and there, blown up on the big screen so everyone at the back could see, was a real live stranger's genitalia of terrifying proportions.
"It's true what they say," Friend deadpanned. "The camera really does put 50lb on you."
That set the tone for an oddly light-hearted hour or so of "installations" including the Loch Ness monster, a KFC Bargain Bucket, a baby bird and a pair of roller skates.
Fine art it wasn't, nor high comedy and I couldn't help but wonder how a couple of Aussie blokes playing with their tackle ever turned into a route to fame and fortune.
But once the initial shock wore off, this was a curiously entertaining show, the performers' laid-back charm somehow making it comfortably non-sexual.
Which is not to say the visiting hen parties didn't whoop it up. Calls for audience participation, however, drew probably the only silence of the night.
