Well, I guess you presently or perpetually have an amazing erection (if the latter, seek medical attention). However, if you are mistaken, it may also be possible "you haven't seen nothing yet" (minding the double negative), and/or lack the information to make an informed decision? Maybe your dick is in a box, and you just don't know whether it is erect or not, yet if you open the box, there is a chance it may have died of radiation poisoning. That or you find the decapitated head of Brad Pitt's love interest. Now wouldn't that be awkward.
