Ladies, please take note if you're ever on tour. It's not all glamour!
"Here's a tip for girls if you ever find yourself having to take a piss in Gatorade bottles: Don't pee with the bottle pressed directly on your hoo-ha, because you might think that this will ensure no leakage and accidental spilling, it actually prevents the pee from coming out because of air pressure. Then if you try to depressurize it, this horribly embarrassing farting sound will emerge from the Gatorade bottle."
