Once in the institute attached to the fabric stands posters with the help of small needles.
In the absence of a third hand, I press a few needles with my lips while attaching one.
Three teachers walked around, they approached me and a dialogue began:

The first (to me): Why do you take it in your mouth? Every man knows that he can’t get into his mouth.
Second: Oh, and I take it in my mouth...and why not?
First, it can be swallowed.
Second: Do you take it yourself?
The first: No, I do not take it!
Third: Take it all in your mouth, so it’s more convenient!
