Lump on floor!

Well. being a dumbass and in a hurry, i slid the jack under the drivers side floor and started jacking it up, not paying attention to where it was. Later i go to get in the car, and theres a bug bump stickin out of the floor! hehe. well. I was wondering, whats the easiest way to bang it down? As you know, theres very limited space (its a 93 cav) on the drivers side to get a good swing with a hammer. I tried the hammer anyways, but it didnt really look like it made a difference. any suggestions?

(yes i know. im stupid. =P)

I would say a hammer get a small sledge hammer or a rubber mallet./

he just said he tried the hammer! do this, get a 4x4 post and set it in there at an angle so one end is toward your seat and the other on the hump. try to keep the pressure off your seat and smack the post with the hammer. there's probably something better to use than a 4x4 but that's the first thing that came to mind
