My favorite at the moment after the most awfullest terriblest worsest miserablest crappiest disgustingest cheesiest prez election in my lifetime is the following...for obvious reasons
"The Moving Finger writes; and, having writ,
Moves on: nor all thy Piety nor Wit
Shall lure it back to cancel half a Line,
Nor all thy Tears wash out a Word of it"
In others words, no do-overs.
