For years, I have been joking about using your own phlegm as glue. I mean, since it was thick enough and also, it was very sticky. When I was small, I tried this theory and it really worked. And now, I have the opportunity to test this theory again. This was because I usually either spit it out onto a tissue paper or swallowed it again. They do taste sweet though....

And so, what you do, to get this glue is to make
yourself sick. Being mentally sick does not count

Dab the yellow stuff onto two pieces of paper and
wait for a few minutes. I mean, if this yellow stuff
sticks in seconds, you are going to have a really
serious problem in your chest...

And minutes later, voila! Ah..... hey. Its not
sticky enough. All it did was to take some
laser toner off and then dried itself up. Either
that, or I am not sick enough.
