This is what I came to mention. Seriously, Sunchokes are the most flatulence producing food ever.
There’s oodles of search results from google on the topic. Take a look!
I grew them for a year or two. Excellent sliced raw or cooked like potatoes. My friend thought it might be a good idea to run them through his juicer and drink the results. Bad idea, he and his wife had to evacuate the home for a while and sit outside.
Excellent point. ALWAYS strategically place oneself near the dog for blame purposes.
Another to chime in on Onion Rings. Especially the ones that are mashed/reformed onion rings (ie, not really made from individual rings of an onion).
Maybe it didn’t hurt YOU but it sure hurt everyone downwind of you 
For me, French onion soup can be lethal to bystanders. But not always, which is a puzzlement. Soluble-fiber gummies, if I take extra (if, er, needed) can make me unfit for company as well.
But the most memorable was 30 years ago. We’d eaten at a place with a soup and salad bar, and they had this yummy minestrone-like soup, and I partook. It was definitely the “gift” that kept on giving :eek:. My poor husband :D!
A friend’s dog has been known to produce room-clearing, window-fogging (dangerous, when that happens in the car!) farts. They were visiting, the dog was holding me down, and he let out a truly shameless fart that pretty much had the paint peeling from the walls. He didn’t move a muscle - there was just this sudden STENCH.
A bit later, I let one rip myself.
The dog got up and left. 
“Yeah, pooch, you can dish it out but you can’t take it!”. Wimp!
I admit, I once blamed the baby when I let one out (no dog handy).
When I was in grade school, decades ago, one kid had this comedy record about a farting contest, and all I can remember was that one of the contestants come from overseas on a cabbage ship.
What was that record?
This reminds me of a joke I heard.
A young man visits his girlfriend’s parents for the first time…
He and his girlfriend’s father are sitting in the living room while the girls make dinner. At the foot of the boyfriend’s chair lies the family dog, Rover. After a few minutes, the young man feels the uge to fart. Unable to hold it in, he attempts to let it out silently, but it comes out audible.
“Rover!” Yells the father.
Feeling relieved the dog was blamed, the young man lets another rip, this time a bit louder.
“ROVER!” Yells the father again.
Feeling one last wave of gas, the boyfriend lets out a nasty, wet, stinker.
"ROVER, GET OUTTA THERE BEFORE HE SHITS ALL OVER YOU! "
The internet knows all, if you know how to ask the question!
