<human>: Give me the gist of the text in a nutshell

It began as a normal day, I proceeded to class with my friends and sat in my usual spot.  Now, lets call this class Geography and my teacher Mr.Beans.  The class began and was all normal until Mr. Beans began to rapidly sip his can of sprite in between talking.  Fast track a few minutes, as the bubbles from his sprite begin to travel up his spouts, he erupts.  Burping mid-sentence and the whole class began to crack up as discretely as they could.  

However, lets take a look at me, being the excited and hormone filled kid I was, I was thinking about the hot girls around, so I failed to hear the teacher burp.  As the peers around me began to laugh, I asked what had happened.  Everyone seemed to just look at me like I was crazy, so I thought they were laughing at me.  I thought about trying to hide my CN Tower within my pants.  Was that the problem?  So I stood up and looked at my friends around me and said, "I'm so tired of being chirped".  It was then that I fucked up.  The entire classes eyes went down to my pants, the Eiffel tower of dongs had been erected through my open fly, making it the mast of the grandest ship, the tower that could not be brought down.  I quickly excused myself to go to the washroom never wanting to return.
<bot>: Didn't hear teacher burp, thought class laughed at me.  Stood up only to have an uncooperative dong sticking out of my open fly.
