- Funny Moments: A lot of the old Looney Tunes gags still had potency, and occasionally, one of the side characters would revert to Breaking the Fourth Wall and become a Deadpan Snarker. This exchange in "The Blabbermouth of Echo Island" was classic:Terry: "How do I know this isn't a trick of the Grump's?"Blabbermouth: "Because-I'm-a-Blabbermouth-and-though-a-Blabbermouth-doesn't-always-tell-the-truth-he-never-lies!"Terry: "Well, how do I know you're a Blabbermouth?"Terry: "Okay, okay, I believe you! Now let's get going!"
- Hilarious in Hindsight: The titular antagonist character has nothing to do with Grump and Not-So-Grump.
YMMV / Here Comes the Grump
