I am so glad to see this thread, I was beging to think I was the only one that simply walks out of the room when someone starts a Powerpoint presentation, I try to make my exit as noisy and obvious as it can be , this I find shuts up aircraft brokers, self important RMC grads and politicians far faster than any others Ive tried, these have included farting out loud, turning the power of in the building or getting our HR girl to go into labour, if a presenter cant make their point without these props then they simply dont know the subject!
