Best/Worst Logos

Excluding allegedly racially offensive sports team logos, the merits or demerits of which are being sufficiently debated in other threads, what are your favorite/least favorite logos, and why? Sports, colas, computers, or whatever, which companies should call a graphic designer pronto?

My personal least favorite: AT&T’s “Deathstar”.

My favorite: Montreal Expos’ baseball team. I’ve always thought the “M”, with the “E” for Expos and “B” for baseball within the “M”, was really clever.

I’d have to rank the Expos logo as one of the worst. It honestly took me 10 years to realize that the main thing was an “M.”

Best logos? I don’t know. For some stupid reason, I really like the Lucent red circle.
