Well, as long as we're telling fart stories...
Last summer in Rome, I was walking to the market one brilliant sunday morning. A friend and I cut through the very narrow streets of Trastevere, away from traffic and noise.
It was such a fine morning, with no noise or people, even my friend and I weren't breaking the silence.
An older fellow (40ish, italian) was walking toward us, and as he passed, I let out one of the loudest and longest farts I've ever heard.
My buddy (also italian) tried to stare me down in disgust but even he couldn't stop from laughing.
I didn't have the balls to look back at the guy, though I'm sure he stopped to glare at the "stupid americano".
