Some years ago, I was walking with my GF through the supermarket, we were looking at the sweets section, right at the end of the isle, when I let a very stinky fart go. I learned over and said we should go.

We walked to long way so we didn’t have to walk through the cloud, 30-40s later, just after we had rounded the far end of the isle we heard:

Female voice: “oh my god, was that you! That is discussing” (loudly) Male voice: “no, it wasn’t me”
Female voice: “why are you lying to me, you are always lying to me!” (Angrily)
Male voice: “but it wasn’t me” (also angry)

I think I may have put the final nail in the coffin of a bad relationship with a fart

My partner and I still laugh about it 16 years later.
