What is the past tense of the word 'crow'?

As far as my English goes, it's not a verb.
Correct me if I'm wrong.

Well Sofie it does have a past tense form according to dictionary.reference.com, it is crowed.

hmm, what does it mean then?

crow2 (krô)

1. To utter the shrill cry characteristic of a cock or rooster.
2. To exult loudly, as over another's defeat; boast. See synonyms at boast1.

Naah. "To crow" and "To crew" are definitely two different verbs, especially if you've rowed at Henley. You may have "crewed" there, and if you won, you "crowed."
