Drew and Kate DID get married at City Hall, almost a year later in "Drew Gets Out of the Nuthouse." The writers must have realized this after this episode and tried to fix it--but messed it up by putting it in as part of the bigamy story.
Why didn't Drew and Kate just get married at City Hall and have a church wedding later? Drew could have gotten the money legitimately without lying to everyone and upsetting them. (I know, it's just a sitcom. But this plot is just so flimsy that it bugs me, especially when it's just such an obvious set-up for breaking them up a few weeks later)
Kate (Talking about her wedding dress from Drew's mom): Your mom must think I'm stacked!
(Drew and Kate are horrified to discover that Beulah Carey has brought another minister to marry them instead of the fake one they hired.)
Beulah: Look, Drew, we brought the same minister that married me and your father.
Drew: Uhh...Yeah, but...Kate and I can only be married by a Catholic priest!
Kate: That's right! That way...our son could never grow up to be pope! See? I can't tell my parents that my son could never be pope! That's just crazy!
Beulah: Oh, Kate. You and your Catholic Voodoo...
Mike McShane (who played the fake minister) and Ryan Stiles previously worked together on the British version of Whose Line is it Anyway?
John Carroll Lynch becomes a series regular as Steve Carey.
Lewis: It's BEAUTIFUL...
One of the movie props in Uncle Cecil's house is the Ark of the Covenant from "Raiders of the Lost Ark." Lewis (as a joke) re-enacts the opening of the Ark (but it turns out that Uncle Cecil's Ark is really just a beer cooler).
