I had a discussion with a friend recently and during that discussion, one comment was "Fitted sheets are really both the best and the worst", of course referencing them as awesome when put on a mattress and the worst when you're trying to fold them.
What else do we have that would qualify for being awesome, but also the worst in a different context?
What?
Ever had an almost empty toothpaste tube that you just couldn't empty entirely and maybe some leaks out later?
Edit: they call it swamp-aste apparently
