A man is fucking a women from behind with her head inches away from the wall. If you prefer she can wear a hard hat. Right as your about to cum you give'r one final hammer and push her head through the wall. Her head will either go straight through the or find the 2x4. Either way you know where to hang the picture.
When the doctor asked me how she got the concussion, I just wanted to tell him about my new Stud Finder.
A modification of standing congress, the stud finder involves picking up the woman and having her lean back. Back parallel to the ground. Approach a wall and begin to thrust while slide stepping down the wall. After putting a couple holes in the wall, find a support (a stud) and promptly hang a picture. Hopefully you'll have a wall full of pictures... eventually.
After doing the stud finder last night a family of 4 ended up in the hospital with broken spines and 4 new Van Gogh's were hung on my wall.
