Easy "working backward" problem?

After dinner, 3 friends leaving a restaurant noticed a bowl of skittles on the front counter. Steven took 1/4 of the skittles but returned 4 because he had a pang of guilt. Al then took 1/3 of what was left, but put 3 back for the same reason. Eugene then took half the remainder but threw 2 green ones back. The bowl only had 17 skittles left after the boys helped themselves. How many skittles were originally in the bowl?
