WASHINGTON -- Amid outraged protester cries about everything from AIDS to war, police did give in to one demonstrator demand: "Bananas!"

That was the only word spoken by a protester in a gorilla costume who hopped up and down outside the District of Columbia Courthouse on Saturday. Inside, some of the hundreds of protesters arrested Friday were being processed.

"He's outraged that they've locked up his brothers and sisters in a cage," another demonstrator said.

About a dozen police officers joked with the gorilla, offering him a sandwich. He refused, instead grunting and voicing his one word request.

The police complied. One ran off and a few minutes later Officer S.C. Braxton handed the gorilla-clad protester a bunch of bananas.

It's not easy being a Trojan horse at a demonstration.

A 15-foot-tall model horse appeared Thursday outside the World Bank. Rain poured down on its wood-and-cardboard skin as demonstrators rallied against oil companies.

The horse was labeled "World Bank Aid," and corporate logos from companies including Enron and Halliburton dangled from its open belly. At a rally Saturday in the shadow the Washington Monument, the horse was joined by an inflatable menagerie -- a 20-foot-tall pig adorned with the words "Hog-tied corporate glutton" and a shark balloon with a globe in its mouth and a sign, "Stop IMF Loan Sharking."
