tsuwm silly, Jo? Now that, I'd like to see!

But--Trix is the name of a cold cereal marketed to children.
In the ads, the cartoon rabbit was forever trying, and only just failing, to eat some Trix, and the children in the ad would say, "Silly rabbit--Trix are for kids!".

I think the Budweiser explanation has been given here before, but that may have been while you were gone. In the ads, the beer truck drives down the road through the swamp, and the ...computerized, I guess...frogs each say a syllable of the brand name, in a deep, "froggy-sounding" voice: Bud...weis...er.

Good grief!! Atomica just reminded me of something I had completely forgotten: Budweiser stands for "Because You Deserve What Every Individual Should Enjoy Regularly". (I didn't even know the internet HAD an acronym finder.) It even had a :-) after the explication.
