They’re just kinda cool! It’s a Marge Simpson thing. You find them at oddity and reptile shows used as part of crafts all the time.

I saw this watching moonshiners on the history channel, so take it with a grain of salt, but the moonshiners were obsessed with them. Since they bend down at the end, you stick the bone into the spigot where the liquid comes out of the worm bucket (where the alcohol vapor condenses into liquid). It directs the flow into a jar. You can also use a stick, but these dudes were always just carrying raccoon dick bones that I’m sure they harvested themselves.
