Problem

Rearrange the letters of the roadside sign "Don't pretend to be what you
don't intend to be" into an amusing English sentence.

Somewhere between Philadelphia, PA and Lancaster, PA, there's a sign
that usually has some sort of cutesy inspirational saying on it.  Like,
"Doing good turns doesn't make you dizzy".  Eech.  Since the sign is made
of removable letters, it can be rearranged into something else.  Here's
the current saying:

    Don't pretend to be what you don't intend to be

The point is to create an anagram out of the phrase.

1. Use as many of the original letters as possible.  Anagrams that use
   all the letters will get the highest consideration.
2. The new phrase/saying ABSOLUTELY can't be vulgar.  Imagine that the
   person who owns the sign has a sense of humor: it should be the kind
   of thing that the person would look at, and be surprised and amused.
3. It has to be a reasonable English sentence/phrase.  I really, really
   hate anagrams that come out like, "Lo, I, a yak?  Sir!  Egg on car!
   Eh?"
4. It should be amusing in some way.

Some details about the sign:
1. There are four rows on which the letters can be placed, so you can
   use them for logical breaks (in lieu of dashes).
2. The apostrophes are actually upside-down commas.  You can use them for
   either.
