Picard, Riker, Troi and Data in the Turbo Lift on the USS Enterprise.
DATA: Captain I'm detecting the growing odour of Methelhydided, Sulpher Dixoxide and Methane eminating from a source somewhere in the Turbo Lift.
PiICARD: DATA??!!
DATA: If I use my Tricorder, I should be able to locate the exact source, Captain.
RIKER: That shouldn't be neccessary Data.
PICARD: Something to hide Number One??
DATA (Scanning with Tricorder): It appears to be eminating somewhere low down in here Captain.
RIKER: It wasn't me!!
TROI: I'm sensing someone attempting to decieive close by.
DATA: Commannder Riker is indeed correct in his statement, Captain, the source is not him.
PICARD: Enough Data, and put the Tricorder away!!
DATA: But Captain I have managed to nearly pinpoint the exact location to somewhere near your proximity.
PICARD; DATA, ENOUGH!!
DATA: Yes Captain.
With that the Turbo Lift reaches its detination and the occupants, apart from Data, emergerge gasping for air.
PICARD (Walking off down the corridor): Number One, have a word with maintainance about inproving the atmosphere cleaners in the Turbo Lifts sometime soon, will you.
DATA: Commander Riker, I do not understand the Captain's behaviour??
RIKER: Data, it is a Star Ship Captain's perogative if he wishes to fart in a Turbo Lift or not. Ours is not to reason why, ours it to but choke and cry!!
