Let's get sick of buying those awful, useless pipecleaners for Father's Day - you know, the ones made of chicken wire and white linen fluff.
They get snagged and rupture and are oft dangerous to boot.
With the completion of the Human Gnome Project, let's genetically engineer worms to like tar
and dirt, and sell them in pack of 15 as pipecleaners.
Then, put them in the end of your pipe, put your pipe out, and introduce them (or one at a time) into your mouthpiece.
They will crawl down your pipe tract, digesting black tar and other pipe-dirt, and excrete chlorophyll, perhaps, into your mouth.
Hence your pipe becomes unclogged, then you can throw the worm(s) away.
