<human>: Provide a brief overview of the text.

So my former math teacher is really awesome, lots of jokes and everything. He usually goes off on a tangent (lol) and tells us random stories (He's got the biggest dog in the neighborhood, proceeds to show a picture of a horse, etc.)(yes, the stories are random, no observable pattern and with different topics every time) and for April Fool's one year, he convinced a lot of people that he got beat up by a drunkard at the mall. We quickly realized it was April Fool's, but we believed it for a lot longer than I'd like to admit. A few years later, we caught his April Fool's stories more quickly, but then one year, he told us about the time he rescued a rattlesnake from the highway and put it back in the wild after it recovered from some injury (or something like that). We didn't think he was that crazy, so we immediately said "April Fool's!" 

He proceeded to show us a video.
<bot>: Teacher tells crazy stories and we take some time to catch the April Fool's stories. One story he tells is too crazy, but it's actually real.
