I suppose it is a Japanese pun. It is also quite common in Japanese humor for characters to wield vegetables as weapons. It is done constantly in Bobobo-Bo Bo-Bobo (from the episodes I have seen, at least), as well as done by the Pokemon Farfetch'd, who wields a leek as a sword. The leek is the most common vegetable used, as evidenced by Vocaloid and the OS-tans.
I am more curious as to why the pedophile has no shoes...
Note: I was talking about the Pedo(phile) character in the picture being hauled off to jail(HELL) NOT the Artist, beidan is MF' cool. Sin, truckingman.
