There's an RMIT computer lab next to our office. I walk past it on my way to the amenities. Right beside the door, there's a big multi-coloured sign that says, "Mobile phones are not to be used in this lab!"

I'm not quite sure why they're so vehement about it. Possibly because they interfere with the delicate navigational instruments of modern-day Macs. Maybe because computer-fumes are highly flammable. Perhaps it's to ensure that no one's just in there googling facts for their friend on Who Wants To Be A Millionaire - this is a serious lab for serious academia!

I'm missing the most obvious point, of course. Because clearly this little RMIT building with a hideous '70s chandelier in the foyer is a blatant terrorist target, but they can't blow up their clever mobile phone bombs if we forbid phones, can they? Foiled again!
