Oooops, I’m an idiot!!
Is there no more open question? I’ll get it rolling again.
Homer’s Exact Doppleganger’s Name
Guy Incognito. [One of my friends has a brother in a band with that name.]
Thursday night
In all fairness, there are probably multiple answers to this one. I just had a specific one in mind.
Bikini underwear is still out there.
By Thursday night, do you mean the night the show aired in seasons 2 to 5? 
Total trivia: this word was a joke on former football player Moisi Tatupu, who was (I think) Samoan. If I remember what I read correctly, he was a running back for the Patriots.
What was the day of an earlier Simpsons time slot?

What is the catch phrase of “Homer Simpson” (not the yellow guy, but a suave character on a cop show that the Springfield Simpsons watch)?
[nitpick]Actually, it was “…the end of that chapter.”[/nitpick]
Bzzzt. I can’t believe no one is getting this one!
I’ll give you a hint: Wiggum says it.
Is it the one where he has a spinoff show in the Big Easy with Skinner?

What are the lines uttered by Lou ("…cat got the rat…) and Chief Wiggum (…the end of that tale…) when the mountain lion apparently captures the giant rat believed to be causing damage in the Springfield Mall (actually caused by Bart & Millhouse while camping in the mall overnight)?
New Answer: “I Do Believe We’re Naked” by Funky C Funky Do
You got it. (I knew if I included enough keywords from SNPP.com it would be a lock).
