Rude Teachers
Me and my friend used to recite this all the time when we were kids. No idea where we got it from!

It is a mans occupation
To stick his knobulation
Up the womans ventilation
To increase the population
Of the younger generation.

I got this information
From the board of education
After a detailed demonstration
Of two teachers on the floor!
