Warning, this has no warning sign

They say this jolly modern world

has gone all PC mad
With warning signs on everything
A health and safety fad
But are we thinking backwards
Should we warn these folks?
Natural select the stupid ones
With warning signs with jokes

Do please now take a hot bath
and use a microwave
Please juggle with these chainsaws
Its time to misbehave

Its really windy weather
you should go for a long dip
please pee upon this electric fence
Unmarked fluid?, have a sip

Of course some warning signage
are needed to get by
But some of them you look at
and say Oh really? Why?
These packets in the old shops
Of nuts containing nuts
Is enough need a warning
of this poet saying TUT!
