The show ends with D.W. yelling "WHO IS DEWEY?????!!!!!!" As the episode still comes to a close, Arthur and Buster say "Ta-dah.", following which they comment on how D.W. much liked the program. along with the comment, "But it would never work on real TV."
"By the way," she adds. "Who is Dewey?"

- A missing book, a stolen pen
- I must remind you to call me when
- You've got something of a mystery
- Call me, Fern detective!
- (Somebody's gotta help me! I'm in big trouble. The writing's on the wall, and the pathway, and the lockers, and it's my name, but I didn't do it!)
- Touch nothing! Trust me, Fern detective!
- First, I'll check the clues
- Muddy prints from muddy shoes
- I'm on the trail
- But this paint just won't compute
- (Buster, get off the clue!)
- (Oh, shoot!)
- (I suppose I'll just have to guess... yes!)
- Buster was out playing ball
- Muffy, in the classroom down the hall
- Arthur wouldn't have the guts!
- J'accuse! (I accuse!)
- (What does that mean?)
- When I crack the big case
- The school will come to me
- They'll ask "Fern, how'd you do it?"
- I'll say "It was elementary!"
- I used my little gray cells
- To deduce who, how and why
- (But I'm telling you, I didn't do it!)
- (Be quiet, Binky!)
- The facts don't lie!
- When your back's against the wall
- And you're afraid you'll take the fall
- When no one else would have the guts
- Call me, Fern detective!
- (Don't do it! Don't call her! I was framed!)
