Out and about we get to see (and in this instance capture on film) some wtf moments. Can you imagine our reaction when we read the sign on the back of this truck. "Please do not push."?

I don't know where to begin with the stupidity of this warning. Look at the size of the truck for one. Even empty, it must weigh over 10 tons.

World's Strongest man

This may be a lawyer's attempt to thwart a repeat of that well-known incident when a competitor in training for The World's Strongest Man pushed a parked-up dumper truck home so he had something to practice on. He never won anything, however, because the event is a truck pull - which requires a completely different set of muscles to pushing.

A new breed of pusher

Can't be too careful these days, either as the new generation of drug dealers are prowling the streets looking for a more respectable way to earn an illegal living. Now you hear whispers between shady characters on street corners,

"What you pushing these days, man?"

"See that truck parked up over there, it's hot shit, pure US product. It's worth a fortune, but I like you man, you can try it out for nothing, no strings attached!"

And finally...

Or perhaps, more sensibly, the funny sign is a helpful advisory on the part of the driver, wishing to remind short-sighted shoppers that his 10 ton vehicle is not a shopping cart. Do not push - truck!

What is the most stupid sign you ever saw?
