TIFU by making a friend pass out on a double date.

I just screwed up bad bad bad not 30 minutes ago. My wife and I invited some new friends out to dinner and a play. We sit down at a trendy pizza place in town and order pizza making light hearted conversation about dietary restrictions (heartburn, etc) when I ask my buddy (tongue in cheek) about any fun weird conditions he has. He tells me he had epilepsy years ago but is a-ok now!

Oh by do I have a story about seizures I can share! Back in high school a stoner classmate lied his way into donating blood and was on the couch next to me, donating. He hollers to me "watch this!" and pumps the little ball and fills up the bag in like 2 minutes flat. The nurse sees this and comes over while he starts to lean up and he promptly turned white as a sheet, eyes rolled back and siezed. Crazy story, right?

30 seconds later when I finish my story, my buddy lays his head on his wife's lap and says "I'm passing out" The three of us laugh. No wait, he is ACTUALLY PASSING OUT. Wait, NOW HE IS PASSED OUT ON THE FLOOR. People freak out, chairs move, the manager comes out on the phone with 911, a nurse pops up from a nearby table. He's starting to come to and when he is aware I ask "is that what your seizures are like?" "No." Then it hit me. It was my stupid story about blood.

Paramedics came, he was fine by then, they left after checking on him after he sheepishly admitted that it was the story that made him pass out.

We laugh awkwardly and try to eat for 15 minutes and we think all is well but he is feeling bad again. He lays down on the floor to get his bearings. Manager comes back out on the phone with 911 again. Crap. Paramedics come again and take him out to the bus to examine. My wife and I quietly pay the bill while he and his wife are with the medics. His wife apologizes to us profusely and tells us she'd never heard of him passing out from talking about blood before. I didn't even know he passed out from LOOKING at blood or I would have kept my stupid fat mouth shut! Obviously the play is out at this point. I am done.

Excuse me while I go die in a corner.

Tl;dr - told a story about blood on a double date, friend passes out and paramedics rush in. Twice.
