We had a sex/std talk at our frat from Student Health a couple weeks ago called "Scabby Dick" with some 40 year old lady. Pretty funny actually. Toward the end she gave us a small paper bag full of durex condoms. One guy asked if she had magnums and so she proceeded to take one and strech it most of the way over her fist to her forearm. When she got it all of the way on she asked if he still needed a magnum.
