There's this old joke (not that funny, really) and many of its variations similar to that picture.
They sent a new type of chainsaw from Moscow to Siberia to test it there. The instructions stated that 200 trees can be felled with it daily.
So Ivan went to the forest, worked all day and felled 150 trees.
"Ivan Ivanovich, that's not enough. You have to try harder tomorrow!"
Ivan cut down 170 trees the next day.
"Ivan Ivanovich, you really have to try harder."
So on the third day again in the forest and he cut down 190 trees.
So they invited an expert from Moscow, who disassembled the saw, inspected it, put it together and set off for the forest. There he started the saw.
Ivan: "Wow, it's buzzing!"
