Worst hand you ever played

Someone posted a thread a while back asking you to tell the story of the best hand you ever played. How about the worst? Do you ever go on tilt and play like a dog, losing all your chips on a hand you shouldn't have been in in the first place?

To kick things off, here's a pretty bad one. Excuse: tired, impatient.

PokerRoom No-Limit Hold'em, $1 BB (10 handed)

UTG ($72.90)
UTG+1 ($47.50)
UTG+2 ($23.75)
MP1 ($53.80)
MP2 ($41.85)
MP3 ($86.80)
CO ($54.65)
Hero ($35.80)
SB ($44.30)
BB ($54.20)

Preflop: Hero is Button with 4, K.
UTG calls $0.50, 5 folds, CO raises to $1

King four sooted, now there's a powerhouse hand if I ever saw one, yep, I'm calling your raise...

Hero calls $1, SB calls $0.75, BB calls $0.50, UTG calls $0.50.

Flop: ($5) 7, T, 5 (5 players)
SB checks, BB checks, UTG checks, CO bets $4

I've hit the flop pretty full on. Flush draw and runner-runner straight possible. Nobody's bluffing me out with any half-assed continuation bet here.

Hero raises to $10, SB folds, BB folds, UTG folds, CO calls $6.

Turn: ($25) J (2 players)
CO checks

Clearly he's taken fright at my big raise. I'm going for the kill.

Hero bets $15, CO raises to $30

Curses. Well with $55 in the pot I suppose I have odds to call.

Hero calls $9.80 (All-In).

River: ($79.80) 3 (2 players, 1 all-in)

SHOWDOWN
CO shows [ A, A ], a pair of aces
Hero mucks cards [ 4, K ], king high
CO wins $78.80.

Here's one of my gems.

My excuse, this was in hour 3, I was losing interest, it was late and there was something on TV I got interested in.

I had just been moved to this table, and I didn't even notice this guy was in the hand until after my braniac all in bluff.

*note to self* Pay attention.

I guess I should be happy to make it to 63rd place out of 1,000 people, but donkey plays like this keep killing me in MTT's
