A shady figure known for drawing the largest breasts on the most unlikely of characters. A menace to the society of online snowflakes who throw a fit over "oversexualization" of characters who aren't even minors. He's also a very nice person, so don't judge a book by its cover!

Created by two guys from East Brunswick in 1987, it is an unofficial tour of the creepiest places in central New Jersey where evil happenings occurred. It is always conducted late at night when the supernatural and followers of the occult are most active. Usually conducted in a large vehicle with six or more passengers. Alcohol is often consumed along the way. The tour guides themselves often set up traps and tricks to freak out their passengers/victims.
