Bleeping is commonly used on television programs that use profane words that are forbidden to television networks. Adult comedies such as "Rick and Morty", "Bob's Burgers", "Family Guy", "American Dad!", "The Cleveland Show", "The Simpsons", "Futurama", "Drawn Together", and especially "South Park" and "Robot Chicken" use this process to block strong curses that cannot be used on television in the United States, and mainly to air it outside the watershed, or safe harbor. The 2008 series "The Middleman", which aired on the ABC Family network, nonetheless included the occasional profanity in dialogue, which was bleeped for humorous purposes (with a black bar or a fuzzy image superimposed over the speaker's mouth). Very rarely, the bleep will be light enough to hear the swear word over it.
