You ever wonder if Kirk pissed off Scotty and found himself transported down to the surface of a planet in a dress instead of his uniform?
I know the internet has rule 34'd this already. But think about the potential Gags and jokes that the transporter could facilitate?
Mr. Scott already did it in cannon he gave the Klingon's a kiloton of tribbles.
You could transport a whoopee cushion onto Mr. Spock's chair just as he was about to sit down.
Transport cadet Crusher into the Alien females only locker room in the nude with a block of ice on his junk!
Mr. Data won't shut up? Transport his head into the cargo bay.
Play underwear bingo and see who notices they are now wearing Yeoman Rand's sexy knickers she puts on for a date with the Captain and not their own standard issue under-roos. My bet is on Dr. McCoy to notice first.
