Blue Bulls

My bull keeps getting out.  
When I was a child my grandmother would always recite the nursery rhyme Hey Diddle Diddle..but come on, how could a cow jump over the moon?  
Well, I've seen it with my own eyes I'm telling ya!  
For the last two months our bull Duke has been getting out somehow, we patch and repair spots we think he's using, only for him to be back in our front yard again come morning. So yesterday, frustrated with his escape artists expertise, I hopped on the four wheeler and started to chase him, cause usually a cow will go back the way he came, then I could know for sure where I need to add an extra row of fencing.  
So as I'm chasing him, he starts running full blast towards a spot I know is strong, and in my mind I'm thinking, good lord I'm gonna have a vet bill if he plows through that fence, I mean it was five strands of brand new barbed wire, but there was no slowing him down at that point. As I let off the gas, worried now that he just might be stupid enough to try it, he jumps and I swear to goodness, clears the five strands with an extra foot underneath left over for error, and clears the fence like he's an expert high jumper of some sort.  
I was in UDDER disbelief 😂  
I swear, I never believed that part of grandma's nursery rhyme, but my mind went right back there, just maybe a cow really can clear the moon after all, and now what?  
The only solution to this now is if the top strand catches the bull by the horns (wink wink) if you know what im saying...  
Lol, only then maybe will he realize green pastures were made for cows...not the moon. ♥
