What is the funniest coincidence you’ve ever witnessed?

I’ll go first I was sitting at Denny’s with a group of teenagers discussing how they would get their revenge on hypothetical bullies and what I assume was a double date in front of me one of the gentleman in the double date picked up his glass to take a sip of his beverage And put the wrong edge in his mouth proceeding to spill his entire drink all over himself, and just at that moment, one of the teenagers yelled in a theatrical voice revenge, throwing his arm up in the air with a fist I had to hold in my laughter as I asked the gentleman if he needed napkins over there and for the teens to handover extra napkins when I left, I damn near pissed myself I was laughing so hard from the situation replaying in my mind
