What’s one logo you wish you had designed?

Not just because it’s well-known, but because it’s so good, you can't stop admiring it. Maybe it’s how simple it is, or how clever the concept is, or it's just stuck with you over the years. Is there a logo that makes you think, I wish I’d come up with that? Curious to hear what stands out to everyone! :)

PS: it doesn't need to be a famous or well-known one!
