Blacktooth the Pirate is the meanest pirate to sail the 11 seas (not including oceans). He is a fictional pirate made up by Grandpa Dave in "The Big Dig." He is a parody of Blackbeard.
According to Grandpa Dave, besides being mean and never brushing his teeth, Blacktooth was also very rich. He had so much treasure, in fact, that it was starting to sink his ship. He decided to bury his treasure, and the nearest port happened to be Elwood City. He drew a map to find the treasure, but it was 20 years before he returned, so he never found it.
