i am always glad to see things "down to earth"...

or perhaps the sign says 'women swear on ground' ?

to quiet their foul mouths you simply need to put them on an airplane.

this sentense needs to be proven scientifically...so, is this comment an invitation to a journey by plane?

nice try jokey !

although i may have some kind of plan: my wife (who doesn't swear) and I will be going on the Eurostar in a few weeks time.

that goes under the ground and under the sea. i'll observe whether she starts swearing.

we should at least be able to narrow down how and when this strange phenominum happens.

i can see we're heading for a rather nice venn diagram.

we all are looking forward to the resulting diagram... ;-) this may help us to understand the real meaning of the sign ... and by this another part of the world.
