The Secret life of the hamburger

As a foetus in the womb of a pig,
was one day born and grew up so big,
he grew up quick, he grew up mean,
so the cut him up because his meat was lean,
put in a machine and processed into mince,
the bloke that done this job, his name is Vince,
it was then shaped into a pattie by my mate,
and then mince was sizzled on a red hot plate,
a young lady served it to me in a bap,
I took a bite and it tasted crap!
