The company that deals with them has displayed examples of the "truly disgusting" items that have clogged Yorkshire's sewers.
In an effort to "demystify what causes blockages," Trinity Leeds created the so-called Cabinet of Curiosities, according to Yorkshire Water.
Alongside unusual discoveries like frisbees and frying pans, such "common culprits" as fatbergs and grease have been put on display.
The company added that non-flushable items had evolved into a "high-end artform.".
Visitors had learned about "a small portion of the world our wastewater team deals with on a daily basis," according to Ben Roche, director of wastewater at Yorkshire Water.
Blockages are expensive to remove, cause unpleasant flooding, and harm the environment, so it's important to avoid them and know what you can and can't flush, he said.
Among the truly "stomach-turning and unusual items" discovered by Yorkshire Water's blockages team, according to Mr. Roche, were boots and cuddly toys.
You might be shocked to learn what ends up in our pipes, he continued.
The business released fresh images in June 2022, taken by its teams as they cleared fatbergs from a Hull sewer.
The nauseating images demonstrated how sanitary towels and wet wipes can clog pipes.
According to Yorkshire Water, clearing blockages cost "millions" of pounds.
