But now you amuse yourself by telling the story to people on the internet? I’m sure he’s so happy about that. 
My cousin (now 14) once had a similar misfortune.
ETA, because it’s hilarious: I, famously, pooped on my grandfather at church once. There are old ladies who now see me all grown up and feel they simply must discuss the incident.
You’ve probably beaten our record… Moon Unit in particular went for the timing thing though. She was 4 months old, and I was getting ready to go back to work. There was a time where I needed to speak on the phone with my soon-to-be new boss (a childless male, whom I had never met). To keep my daughter from fussing during the call, I got her latched on to nurse. She - as many babies do - pooped almost immediately. Oooookay, well, she can sit in it for a couple of minutes, won’t do her any harm.
Then the poop began to leak. Drenching her clothes, and then mine. At which time I hastily excused myself.
A few days later, I needed to speak to the fellow again.
EXACT SAME THING HAPPENED.
I decided his voice must have a long-distance laxative effect.
Dweezil was more into the projectile pooping - in mid-change. Once, he got the diaper changing surface, the sheet (he was being changed on his crib), and the crib bumper. Another time he got the changing surface, and the rug 4 feet away.
Then there was the time when he was about 2 years old and I’d been out for a Moms Night Out. I got home, and apparently he’d pooped a couple of minutes earlier. He was at a stage where he fought diaper changes pretty violently, and it was nearly bedtime, so I concurred with Typo Knig’s decision to let him stew for a few minutes.
Then Dweezil climbed up onto his bed, and began jumping.
And BALLS of poo started falling out of his romper and onto the mattress and rolling onto the floor. Whoops! One of us pinned him down and changed him, while the other one had to retrieve the errant output. BLECH!
You know, I listened to three Brazilian Girls songs yesterday, and aside from a mild headache, I was fine. Though I dislike them (I was listening to new songs to see if I still do. yup), I think that throwing up was coincidental 
We recently visited some friends who unexpectedly invited us to stay the night. No problem, we had two extra sets of baby wear for our almost three-month-old girl.
So far, so good, until the series of blow out poopers. The friends don’t have a dryer, so after we ran out of anything wearable, we washed her dirty ones and used the hair dryer to recycle.
I honestly don’t remember what our record number of changes was for any of the kids as babies.
But we went through about 12 sets of undies and trousers on the Smaller Girl last Friday. Been better since then - today was only about 4 or 5.
Toilet training. A joy which is still ahead of you…
