  • A particularly juvenile Mother Goose poem-thing:

    "I am a gold lock."

    "I am a gold key."

    "I am a silver lock."

    "I am a silver key."

    "I am a brass lock."

    "I am a brass key."

    "I am a lead lock."

    "I am a lead key."

    "I am a don lock."

    "I am a don key!"

    Reminds me of the old (equally lame) joke...

    "How do you spell spot?"


    "How do you spell spot?"


    "How do you spell spot?"


    "What do you do at a green light?"


    "You stop? At a green light?" (cue Nelson: "Ha ha!")

  • Yes ceebee, this word absolutely does sound like the braying of a donkey, yes! I've always thought so. In my mind I change the 'n' to an 'm', so I get "dommmmmm-keeeeey!"

  • It certainly isn't.

  • I found, when still a child, that if you say this word juuust so, it can sound like the animal's bray... which is why I'm putting it on my list now... :)

    Edit: is the WordNet definition really the most common usage?

  • This for me is probably the funniest word to hear out loud in the entirety of the English language. Anything can be made laughable with the simple addition of the word donkey attached to it. ;)
