Beach or got to the pool?

It must be me being an idiot but I spent ages trying to work it out and only just sorted out that it was, in fact, related to the placement of a tube into the mouth and having ones face in the water.

Wow what a smart-arse! I couldn't work it out at all

Yes, yes ... I'm an idiot

Please go swimming in the sea - we may get lucky and you may be eaten by a shark
