MATT: Fraggles are a noble race; fearless, dignified, intellectual.
BONK! Fraggle hits his nose on a stalagmite! Classic!
To FraggleRockRock... with all due respect, when reading what you've found funny in the episodes, something tells me you haven't exactly been exposed to a whole lot of comedy in your life so far.
I always liked how, when someone would use a big word, Wembley would respond with describing what that word actually meant. It was really unique that he taught little kids words like 'extinct,' 'parched,' and 'amnesia' with an innocent touch of funniness.
As I got older I found Boober's pessimistic attitude somewhat funny. I like how he can sometimes seem like the most 'realistic' and 'human' Fraggle of the group in how he responds to the rest of the group.
Red seemed to have a few funny parts that had to do with Wembley. Most notably, in "Gunge, The Great & Glorious" when she tries getting Wembley away from Philo and Gunge... "Wembley... say good-bye."
Mokey's the blissfully fun woman of the group. Usually when she makes me laugh, it's because what she's just said is so sweet and innocent that you can't help to not only laugh, but want to give her a big hug for being so cute. Case in point, "Bored Stiff," when she suggested they go talk to the Gorgs... "Besides, I think that big, brown hairy one kind of likes having us around."
When Gobo does or says something funny, I've noticed that it's been when he's just egging the conversation on. In "Gobo's School For Explorers" he tells Red that he should join Boober's school of laundry because it's more her speed. Granted, that's not always the case, but since Gobo's the serious male of the group, it's only fair he keeps a cool head most of the time. Kinda like Kermit.
