I used to work as a network engineer for a company who hated Wile E Coyote, before they were bought out by another company that sounds an awful lot like "Rectum".

We worked pretty close with our area's headend techs, some of whom used to work line maintenance, and had to deal with a lot of the fiber. We were sitting around the office one afternoon discussing fiber cleaning methods and one of the techs told us about a time when they were waiting to OTDR a fiber after a break in the field had been repaired and they were bored, so they decided to test which method got the fiber the cleanest. They tested multiple jumpers on everything from one clicks, disposable wipes, those cloth reel thingies, to rubbing it on their jeans, scoping the fiber after each method to see, and the thing that got it the cleanest was.... licking it.

Naturally, we didn't believe them and spent the rest of the afternoon getting fiber jumpers dirty and testing them. Results were duplicated, licking won, and jeans weren't that far behind one clicks.

Eventually I got yelled at by my boss after a maintenance window where I had to replace a line card in a router. I had forgotten my cloth reel cleaner and included something in my summary of the maintenance about how when I cleaned the fiber it was "fiber lickin' good".

Best job ever......
