If you done it, it ain't bragging.

It's not bragging if you can back it up.

I think I may be in - potentially - three classics. That sounds like I'm bragging.

And I saw on this hill, since my eyesight's so keen, the two biggest fools that have ever been seen! And the fools that I saw were none other than you, who seem to have nothing else better to do than sit here and argue who's better than who!

Mere flimflam stories, and nothing but shams and lies.

If you done it, it ain't bragging.
