That reminds me of when I was a kid, farting in the bath. As I saw the bubbles coming up to the surface, I wanted to catch them.
So I took whatever plastic container I could find around the bath - most likely the cap of a shampoo bottle - submerged it, and held it close to my butt when I felt the next fart coming.
I succeeded in catching some of the fart in the cap. Then I claimed my prize by sniffing directly from the cap. It was so much worse than any fart I've ever smelled.
As a true scientist, I've repeated the experiment on a few later occasions, and without a doubt : bath farts captured in plastic containers smell much worse than normal farts.
Each time looking for it for at least 10 minutes, so this time I'm going to put it at the logical place.
Time passes...
Looking for hours at the four logical places I could've put it, then giving up. Coming across it a week later and thinking "well that IS a logical place for it to be"
