What would you do if the person above you was-

[Arwena]

Scream for help - what else?

WWYDI you later found out you were invisible only to yourself?

[Interference]

I think I've had that nightmare

Probably cut myself shaving loads of times before it occurred to me to go to a barber.

WWYDI your barber/hairdresser/stylist turned out to be an alien with no sense of touch?

[Arwena]

I think I've had that nightmare

WWYDI everyone in the fashion industry turned out to be an alien?

[Interference]

I'd try to act surprised

WWYDI David Bowie turned out not to be an alien?

[Arwena]

I would conclude it's a mad,mad, mad world

WWYFI Liberace turned out not to be an alien?

[Interference]

Try not to act surprised

WWYDI Sergeant Bilko was in charge of the Alien Welcoming Committee?

[Arwena]

Serve on the Committee with honor and distinction, sir (*chuckle*)

WWYDI the head of the alien delegation looked exactly like Sgt. Bilko

[Interference]

Lol

Worry and hide my month's pay.

WWYDI the alien then offered let me in on a deal he has going involving a horse and a set of headlamps off a jeep?

[Arwena]

Take a chance, maybe aliens are actually honest

WWYDI the aliens ordered that we all wear some kind of uniform to mark our place in society

[Interference]

Ask Fender to make sure mine had a sweep to the lapels.

WWYDI the alien's commanding officer had a dazed look on his face most of the time?

[Arwena]

I'd take it for an alien smile

WWYDI the aliens fell asleep while they were being welcomed by the Prime Minister (or president, if you wish)

[Fal]

Explain to them that they shouldn't feel embarrassed, it's just Brown for you.

WWYDI It was announced that the Government had sold off your town so the aliens had somewhere to do their experiments?

[Interference]

Hope their experiments involve chocolate pudding and lots of ice cream.

WWYDI the aliens took all the chocolate and ice cream in the world and put it in one small sea-side town on the east coast of Ireland?

[Arwena]

How many visitors could the East Coast of Ireland hold???

WWYDI the aliens only liked vanilla ice cream?

[Fal]

Nuke them

WWYDI the experiments they had been doing, regarding ice cream, meant that your town had been turned into an arctic environment, but all the ice/snow was flavoured?
