Redundant phrases seem to creep easily and often into our common usage.   Not to mention frequently.

Some of my favorites (or I should say the ones that cause the most eye-rolling) are:
- Deja vu all over again (Thank you, Yogi!)
- It's a win-win for everyone.
- 8:00 AM in the morning
- HIV virus
- PIN number

You may have others in mind.

Then, of course, there are the musically related ones, such as
- out of tune banjo
- loud drummer
and
- arrogant soprano

Anyway, anyone have others to contribute to this unimportant and inconsequential thread (which is far from monumental in significance)?
