<P> Though he clearly teaches life lessons and even offers valuable insights to The Gang, Frank's worldview is often very skewed . In the episode "Mac and Dennis: Manhunters," Dennis remarks that some of the stories Frank tells of his life come straight from John Rambo's life . In "The Gang Gets Held Hostage," Frank emulates John McClane from the Die Hard film series . In the episode "Mac Is a Serial Killer," Dennis says Frank "makes less and less sense as the days go by," and in the episode "The Gang Gets Lost in The Woods," Dee says to Frank "I just don't question the things you do anymore ." Frank has displayed diminishing mental capacities as the show goes on, often seemingly to forget what he's saying in the middle of a sentence, which may be shaped by a lifetime of substance abuse . </P> <P> He has a tendency to trip on LSD, where he has manifested traumatizing experiences being trapped in the bathrooms of recreational vehicles . Like the rest of the Gang, he often drinks alcohol, but usually not to the excess that the others do, except in the episode "The Gang Gives Frank an Intervention ." Frank is also notable for his recreational use of marijuana, using the drug with a higher frequency than other members of The Gang . He often does cocaine right before introducing a scheme to the Gang . Frank has shown extreme violent tendencies and, unlike his cowardly friends, seems to relish physical confrontations and inflicting physical pain on others . He is known for carrying around a snub - nosed revolver on him at all times, producing it whenever and wherever he or others in The Gang feels it is necessary, pointing it around, even firing it, mostly at inappropriate times, such as when he thought there was a grease fire in Paddy's in the episode "The Gang Gives Frank an Intervention ." In the episode "Mac is a Serial Killer", Frank is eager to use a chainsaw on Mac when he becomes convinced that he is a serial killer and appears to be about use the chainsaw on the real serial killer at the conclusion of the episode . In another episode, Frank waterboards Dee in a urinal, in order to gain information from her . In the episode "The Gang Gets Held Hostage," Frank tried to ensure Charlie be murdered to protect his own will and, in "The Gang Goes to the Jersey Shore", Frank nearly murdered Mac in competition over a "rum ham" when the two accidentally go adrift at sea . </P> <P> Frank appears to be very wealthy, apparently making his fortune from his former real estate company ReyHam Properties, from which he swindled his business partner Eugene out of his share of the company, as well as foreign business deals, such as a Vietnamese sweatshop; He also makes vast amount of money through crooked business schemes such as purchasing a stake in a gun store, and then making the public anxious about crime . Despite this wealth, Frank prefers to live in squalor as Charlie's roommate in an apartment referred to by anyone who dares step into it as "a shithole," which originally stemmed from his desire to hide assets from his then recently separated wife . </P> <P> Since then, he has gone through a consistent and prominent devolution and becoming more and more cruel, selfish, and greedy as the show has progressed . He will do anything in his power to sleep with women (seemingly any woman), frequenting strip clubs, prostitutes and almost joining (along with Dennis) a group of swingers . Frank even happily bedded "the waitress", Charlie's long time object of unrequited love . Frank was initially aghast when he learns Dennis and Dee are not his children, upset over their divorce, and appeared to be overjoyed when his long - time wife dies . At one point, Frank tries to have sex with his niece through marriage, the grotesque "Gail the Snail," but they only wind up dry humping after consuming several Monster energy drinks . In "Frank's Pretty Woman", Frank was prepared to settle down with a nasty prostitute but was then completely indifferent when he learns that she died from a crack - cocaine overdose . </P>
