They say it's lucky
If a bird "hits" on you... how?
Would it be luckier
Being dumped on by a cow?
I've been hit enough
And my lucky bag's not full
Bird or bovine
It's all cock and bull!
Hahaha nice punchline! Indeed luck is most likely a long chain of cause and effect, and all those chains colliding into each other causing yet other chains to be created.
