If Led Zeppelin plans on reuniting, they have a funny way of saying it.

During a news conference Tuesday promoting their 2007 reunion concert film, "Celebration Day," the band became uncomfortable with a question about "anticipating something bigger for the band."

"We've been thinking about all sorts of things, and then we can't remember what we were thinking about," Plant said testily. He then referred to the reporter by the pejorative term "schmuck."

Throughout the news conference the band fielded questions about a possible reunion, often responding with stoic silence.
