Classic Poem

If I could get to heaven
By eating all I could,
I'd become a pig,
And I'd gobble up my food!

Or, if I could get to heaven
By climbing up a tree,
I'd become a monkey,
And I'd climb up rapidly!

Or, if I could get to heaven
By any other way
Than the way that's told of
I'd 'a been there yesterday!

But the way that we are told of
Bars the monkey and the pig!
And is very, very, difficult,
