I hope it isn't to awful or humiliating. I found this about Lady One Question:
How long is Mr. Handshakingman able to shake <random celebrity>'s hand. Is it a) 0-30 seconds, b) 30-60 seconds c) 60-90 s, d) 90-120s or e) 120 and more s. You then get a few seconds to place your bets, and then the answer is revealed. The longest I've seen was him shaking Thora Birch's hand for almost 3 minutes, while interviewing her about a movie and turning away after each question and translating what she said into japanese.
A slight variation on Mr. Handshakingman is Lady One-Question. She asks someone one question and when he/she's done answering, she just keeps that same facial expression and doesn't ask any further question. So how long until <celebrity> walks away
Can you imagine Helen keeping quiet???
