over the moon

me: how could a cow jump over the moon?
you: simple.
me: but it's not biologically or scientifically possible.
you: And why might i ask is that?
me: because a cow just can't jump that far into outer space (or into outer space at all for that matter)
you: well if you were asking me in the beginning then why question my advice?
me :but it's not advice at all.
you : well what ever then ,just don't ask me if you don't want my opinion!
