That is harsh, especially for it to happen twice in such a short period.
Reminds me of a hand from several years ago when we first started playing 1/2 at our home game. Up until then we'd been playing 0.25/0/50, $40 buy-in game. So even though the final pot size of almost $1000 wasn't outrageously huge by $1/2 standard, it was quite a bit more than we (at the home game) were used to seeing.
Hero had 9

9

, raised to $12, one called. Flop was 9

8

2

.
Hero checks, Villain bets $25, Hero raises to $100, Villain goes all-in for about $450 total.
Hero has the nuts, so he obviously calls. Villain tables A

8

for middle pair and a backdoor flush draw.
Turn is the :8

. River is the 8

. Villain takes the pot with runner-runner quads. Granted he also could have won with runner-runner aces or runner-runner hearts, but it was still a terrible beat nonetheless.
