Cook some noodles in boiling water, pour off the excess water, and let the noodles cool off. Then make a penis-size hole in the pasta, which should be fairly stuck together at this stage. Then away you go. The wet pasta should be enough for a lube. Caution: Don't be too eager with this one – to avoid burning yourself, the pasta must have cooled enough so you could hold a finger inside it without any problem. And please, don't serve the pasta to your family afterwards!
