Seems like a silly request to me. That's actually a legitimate paper, just the title picture was funny. Oh well. Do you remember... wasn't there a paper in JACS a while back about some NMR "P.E.N.I.S." experiment (Polarization Enhanced Nuclear Inversion Spectroscopy)? That was legit, too, although also rather amusing in subject. These things do 'pop up' from time to time, and though they are funny, they are actually legit new science, which is why I placed it here rather than the humor forum where we get e-mail forwards and other things. I put the 'porn' title on it to catch people's eye.
