A flying disk that looks just like the classic U.S.S Enterprise!

From Thinkgeek:

Each Star Trek U.S.S. Enterprise Flying Disc is pretty much just what it looks like. There’s the saucer section (made of space-age plastic) which is the part you throw (just like a regular flying disc). But the Star Trek U.S.S. Enterprise Flying Disc also has the rest of the ship attached (made of foam). The saucer section spins freely, and the secondary hull actually stabilizes and flies behind it. The result? A U.S.S. Enterprise you can easily throw and catch.
