Rarest/Most Unusual Poker Hand?

What's the rarest/most unusual poker hand you've ever had?

Once I had the exact same 7 card hand as someone else. Same straight, same other two cards, and not Texas Hold'Em either. Not sure exactly what the odds of that are, but I've been playing poker ever since I can remember and only remember that once.

Rarest would be either T-A Straight Flush or 4oak Aces (obviously T-A SF > 4oak Aces).

Most unusual - I've had the same hand as others many times (not same exact cards, but same numbers, ex: both have 3/5 of some sort).

Yeah, meant same numbers (standard deck). Really, all 7 cards the same?

No Limit Texas Hold'em is all I play/have played so no, not seven.
