This is how I used to sing it, have fun

THEY'RE ONLY KIDS

There's Lego in the toaster and there's Lego in the loo
Look before you swallow cos there's Lego in the stew
Don't tell the little b**buiders what you'd really like to do
Just remember they're only kids

And isn't it exciting when the words begin to come
You teach them to say Daddy then you teach them Mum
And then you try to shut them up when they discover bum
Just remember they're only kids.

And it's Mummy we've been helping, Mummy why have you gone pale
Look what's in you handbag, we've been collecting snails
And we nearly fixed the Telly but we've just run out of nails
Just remember they're only kids

Granddad's in the bathroom and the air is turning blue
The kids have plugged the keyhole with a tube of super glue
And he didn't see the clingfilm that they'd stretched across the loo
Just remember they're only kids

The magazines they read are on the purple side of blue
They know where babies come from and they know what makes 'em too
And with action man and Cindy they'll show you a thing or two
But just remember they're only kids

And now the years have passed and your little birds have flown
You're off the tranquillisers and it's home sweet home
And then they come to visit you with children of their own
Just remember they're only kids
