Houston! We have a problem!

Religion must be

a blind faith,

cos no one knows

where heaven is.

Excuse me Sir!

Do you know the way to heaven?

No, sorry I don't.

But I know the road to San Jose!

Are you religious?

Yes I am.

But you don't know where heaven is?

Nope!

Do you pray?

Of course! 

But no directions are given?

What about the stairway to heaven?

You'll have to ask Led Zeppelin about that.

Apparently, the lady knows and 

she's buying.

So no-one knows?

Nope! Its the blind leading the blind!
