I swear, with his house you'ld think he would have more action than the whole town. I simply love it when he starts hitting the remotes and everything changes! But...What I'ld like to know...has he ever been shown with a girlfriend??
He did actually get married in one episode ... to a maid Peter won as a prize and underwent a complete transformation. He was jolted back to his senses during the wedding reception and when he tried to end it, his wife threatened suicide. The guys then helped Quagmire fake his own death seeing this as his only way out. During his funeral the grave was to be cemented over (Adam West's new precaution to prevent an outbreak of zombies!) so Quagmire had to be quickly resurrected. However "Death" arrived for the body, so they suggested he take the wife seeing as she was suicidal anyway ...
