As we go about our daily lives, our paths cross with many other people. Some we know, others we have never met and will never see again. During these brief moments of convergence, the most unlikely scenarios can be played out. We might bear brief witness to someone's implausible drama-by-cellphone, or a freak mischance involving a carbonated beverage. A few seconds later, we've passed on by and the people fade from our memory just as they fade from our lives.

However, the wacky and outlandish events that sometimes occur stay with us.

What's the strangest/randomest/funniest thing you ever witnessed while you were going from A to B?
