GeekDad Puzzle of the Week — Random Word Search

This week’s puzzle is really straightforward: how many distinct “word-tile game” dictionary words can you find in the word search grid below?

The challenge? The grid is randomly generated using a slightly modified frequency distribution of standard English language texts. That is, E happens about 12% of the time, Q right around 0.095% of the time, etc.
As always, please send your responses into GeekDad Central, and all correct (or at least reasonably well-reasoned) responses will be entered into a drawing for this week’s fabulous prize: a $50 Gift Certificate from the hard-working team over at ThinkGeek.

For your convenience, and to avoid typing errors, a copy-paste-able version of the grid appears at the end of this post.

BONUS: For an additional chance at this week’s prize, also list the longest word you were able to find.

Good luck, and happy puzzling!
