so this dude dies and goes to heaven....
jesus meets him at the gate and starts to show him around....

'here we have the dorms, feel free to decorate as you like...... oh! these are the tennis courts, there are always enough tennis balls.... and here is the cafeteria, don't worry, everything is free!'

jesus guides the dude to this one VERY long hallway with a big heavy door closed tightly... he turns to the dude, puts his finger over his lips and whispers 'shhhhhhh'
he opens the door, motions the man in, and closes the door tightly behind him.
they walk quietly down the long corridor and get to another door, heavy as the last, and walk just as quietly through it.

once the door is closed jesus continues...
'here is the pottery room... there is always someone around who knows what they're doing if you care to learn...'

'uh... jesus?' interrupts the dude

'what's up?' jesus asks

'well... i was just wondering... whats up with that hallway? why'd we have to be so quiet?'

'oh... thats where the jehovah's witnesses stay, they think they're the only ones here'
