There's nothing quite so scary as an angry man in undies. Make that any man in undies.
I have some experience of a raging undie-clad bloke - unfortunately I was laughing too much at the time to be really frightened, and worried if we'd ever be able to talk to our neighbours again, to really enjoy the moment.
I salute Ohaupo farmer Arnold Reekers who had to find his inner undie angry person when thieves tried to pinch his quad bike at 3am and he took off after them in a high speed undie 500. He warns that angry men everywhere will take to arms in their undies should thieves continue to threaten their property and peace of mind.
I believe him.
My signifying other who continues to rewrite the way the normal world should be, once had to spring into angry undie action armed with nothing but a sling-shot.
