Flop is beautiful, gets worse from there- NL600

[mindless]

At work, so no history. UTG (about 40/10, reason I'm at the table, got about 600) limps, followed by MP limper (maybe 35/15...also sucks, has about 800) and then I call in the SB with J [img]/images/graemlins/spade.gif[/img] t [img]/images/graemlins/spade.gif[/img] and 1000 behind, and the BB (probably one of you guys, running at 22/15 or something, has me covered) checks.
