H2G2.com: irregular verbs
Being a big fan of the "trilogy" of five books, I need to explore the H2G2 site more.
My favourite character in Yes, Minister/Yes, Prime Minister is Bernard, who often was pedantic about figures of speech, and would annoy his colleagues with "another one of those irregular verbs".
P.S. "Irregular Verbs" would make a great blog title/domain name.
