First they decide to do good: Sweet Dee and Mac adopt a baby that was abandoned in a dumpster, Dennis volunteers with environmental rights activists, and everyone in the gang become vigilantes to solve Philadelphia's homeless problem.
I feel like you’re saying “boy’s hole”, and it’s clearly “soul”.
Charlie goes to great lengths to woo her, while she goes to great lengths to attract Dennis' attention.
He is also present at the end of "Dennis Gets Divorced" where he works pro-bono for Maureen Ponderosa, securing a deal with Charlie's Uncle Jack Kelly, who is a lawyer, where Dennis can keep his apartment in exchange for assuming 90K of Maureen's debt.
Two members of the gang find themselves on the wrong side of the law due to mistaken identity: Mac is suspected to be a serial killer after becoming distant from the gang and Dennis is mistaken for a registered sex offender after a real sex offender (who looks like a fatter version of Dennis) is released from prison due to overcrowding.
This gang is made up of a bunch of despicable human beings, but we can't help but love them.
