How to play a hand?

[thenutts]

Third hand of a multiple table tournament in the big blind. Four people call, small blind folds, I check. I have J 4 offsuit. Flop comes J 4 2 rainbow. What do I do? My thinking was to end it right there. I tapped and got called by one player, who had J 8 off. The end is irrelevent, but did I do the right thing? (He hit an 8 on the turn)
