We stopped by the start of Les Parfaits accidentally last week. We physically could not move once DW said "there's a guy with a bag on his head playing the clarinet"...
So we watched for about five minutes as a juggler worked to set up a skit - five minutes of pretending to juggle with various guests (not actually juggling, mind you) until they announced inclement weather was coming. I have no idea what type of trick or joke he was setting up, but for a show that lasts probably 12-15 min tops, he burned up a third of it without a single "ooh", "ahh", or a laugh. Unbelievable...
