All of The Big Frog, where after Norbert snaps at Dagget to grow up and stop playing with his baby bunny dolls yest he'll embarrass them. Strangely, Dagget shrugs and complies... and the next scene has him acting like a Bumbling Dad, with over-the-top clothing trends (such as many reading glasses and pants tied up above his waist) and doing all sorts of 'mature adult' things like getting Norb to eat his stew instead of chips (healthy food), swinging his golf-club to work while saying any number but 'four' as he leaves, and literally 'bringing home the bacon'. It's breaking down Norb's normally cool and collected persona... and WORKING.
And much later, Norb starts regressing to a childlike state and playing with Dag's bunny dolls, to which Dag joins in and pretty much states he was doing the whole thing on purpose just to mess with Norb.
"There's an alien invasion in the bathroom!"
Dag's "hook" persona in Things That Go Hook In The Night. With such tidbits as "Not sharp enough! NOT SHARP ENOUGH! Try it on him! You'll see! YOU'LL SEE!" And:
Dag/"Hook": Sing with us! Sing with us, silly beaver! Sing "The Happy Hook Song!"
