Oh god, here goes...
Returning from an Outward Bound week with a group of kids in the minibus and I was driving.
Devante (aged 11): Tony, can you stop the bus? I need a wee.
Me: No mate, sorry I'm on the motorway and it's crawling, you'll have to wait.
D: But I'm busting.
Me: Sorry, but I can't stop even if we are only going slow.
2 minutes later...
Earl: Eeew Tony, Devante's pissing in a bottle!
Me: Ok, just leave it, screw the top on and put it down by your seat.
10 mins later...
D: Tony, I need to go poo.
Me: Absolutely not Devante, I can't stop, wait about 15 minutes until the services.
D: But Tony, I NEED to poo!
Me: NO! Stop being silly and wait.

Earl: EEEEWWW TONY, DEVANTE'S BUST A SHIT IN A BAG!!!!
Me: I hope not, Sue (another leader at the back of the minibus) can you sort him out.
Sue: It's true, he's crapped into a Tesco bag.
Me: Oh God, well tie a knot in it and hang it out of the window then close the window trapping the bag outside.
a couple of minutes later the traffic started moving faster, the bag then started to flap against the side of the van... ping, off it went flying behind and landing full-on onto the black cab window behind us.
This is a true story.
