Here's some brain-scanning humor from the University of Western Ontario's Psych department site:
9. While pouring syrup on your Eggo waffles, you note that you missed a few voxels.
8. Your knowledge of brain anatomy exceeds your knowledge of geography. As in, "The transverse occipital sulcus intersects the intraparietal sulcus near the level of the parieto-occipital fissure" and "The Sahara is in Afghanistan, I think."…
5. Friends wonder how you can run a four million dollar scanner and still fail to program a VCR.
4. You suffer frequent left/right confusion and find yourself saying things like, "Make a left turn at the lights… No, I meant a *radiological* left!"
