Two Clerihews for Bill Bryson

Said Grandpa to smug Bill Bryson
Please try for a little less wry, son.
If that's the fame you give Iowa,
They'll subpoena you in Hiawatha.

Said I to his Englishness Bryson,
I've read your book, twice, on
the history of all that you knew,
but you've clean left out Clerihew!
