Suck out of a suck out being sucked out

I was spoiled not playing on Poker Stars for a while when I decided to come back....

UTG folds, UTG+1 folds, MP1 calls, MP2 folds, CO folds, Button calls, SB completes, Hero checks.

Flop: (4 SB) 2:spade:, J:spade:, 8:heart: (4 players)

Final Pot: 15 BB

Results in white below:

I did nothing but shake my head and laugh.
