"Dennis Looks Like a Registered Sex Offender" is the eleventh episode of the third season of It's Always Sunny in Philadelphia.
It was released on November 17, 2009, and aired on December 16, 2010 on FX as the last episode of season 6.
A video disclaimer on the Blu-ray release indicates it was not filmed in high definition, but was upconverted.
Dennis is repeatedly implied to be a sociopath, and in one episode was diagnosed with borderline personality disorder and prescribed medication. He is revealed to be an atheist in the season 7 episode "Sweet Dee Gets Audited." Multiple episodes have shown Dennis to be bisexual, often as a result of his pandering to attention or his need to "get off" no matter the situation.
His sense of self-worth is entirely dependent on what others think of his appearance and he often suggests the best way to sleep with a woman is to make her think she may be raped or by using his personal system, the D. He is also a big fan of the music of Rick Astley, Bryan Adams and Steve Winwood. Deandra (usually called Dee or Sweet Dee) is Dennis' twin sister, the main bartender at Paddy's, and the show's main female character.
They don't count her as one of the gang, but rather as just someone who works for them.They run Paddy's Pub, a struggling South Philadelphia Irish-themed dive bar. Mac is the wanna-be bruiser forever stuck in adolescence. In the second season, Danny De Vito joins the cast as Dennis and Dee's neglectful father Frank, a shady businessman who is drawn to the gang's depraved lifestyle. Dee dreams of becoming an actress even though she has no acting experience and no talent; however, she deludes herself into falsely thinking she is a talented actress, comedian, and singer.Like her brother, Dee is egocentric and often states that she thinks she is talented and pretty, although she is constantly told otherwise; as an example, she has been told she is "a disgusting whore" and "looks like a Holocaust victim". Frank is the legal (but not biological) father of twins Dennis and Dee, and possibly the biological father of his roommate Charlie.It is heavily implied throughout the series that Mac is gay, even momentarily coming out of the closet in season 11, and again in season 12, although this time permanently. Dennis is Deandra's twin brother and co-owner of Paddy's. Some episodes hint that Dennis may be a serial killer and rapist, though this remains ambiguous, with one episode suggesting that he collects suitcases made of human skin.He also displays anti-semitic views, driven by his Catholic upbringing. He is narcissistic, selfish, histrionic and vain, perpetuated by his Ivy League education at the University of Pennsylvania. He even threatens to kill his sister, cut her body into small pieces, and put those pieces into a glass box and put it on display.PM on a Tuesday The Gang is affected when a local prison has to release a quarter of its inmates. Mac's dad is released and comes back into his life, while Dennis has to deal with resembling a released child molester.
