Talk about tight? Strangest stats I've ever seen.

[BigBluffer]

I was playing some low-limit HE yesterday, clearing the Empire bonus, when I noticed these strange stats from one guy:

Hands: 238
VPIP: 0.45% (1/238)
PFR: 0.45% (1/238)
W$WSF: 5.26% (1/19)
W$@SD: 20.00% (1/5)
BB/100: -11.66

He only showed down 5/238 hands.
His only PFR was with QQ (did he get 0 AA and KK&gt
His only win at SD was with 62s (from a blind)
His other SD's were with KJo, K3o and 97o (all from a blind)

Any reasonable explanations for this kind of play? I can think of 2:
1. Total noob just hoping to hang in there while clearing a bonus. He probably won't make it - he's losing almost $20 per 100 raked hands.
2. His bot is broken.

What are some of the strangest stats you guys have come across?
