Here’s one from one of my favourite episodes:
Char #1 “Help me Lion-O, Help meeee”
Lion-O “Hey turn down the lights! Pretty lights.”
OH i know this one!
Queen of 8 legs!
YAY!
And character #1 was Mumm-ra in the shape of a diamond fly with a really high pitched voice…haha
I just saw that episode again and he’s right. Lion-O doesn’t believe it at first and then Snarf says something like you’re grown up now.
It’s your turn Sepphara.
Alrighty here we go
“Lion-O one time Lord of the Thundercats. One time?? We’ll see about that!”
Episode and who said it!
Wasn’t that Lion-O in Fond Memories? Mumm-Ra was disguised as Dr. Dometome and lured Lion-O and the others into a trap with living portraits.
aero you are right my friend!
Here’s one that might leave you swinging at air…
“Stronger than me? Not likely!”
Good choice!! It belongs to one of my favorite episodes,if not my favorite!, so i’ve memorized most of the lines there!!
Episode 11-The Ghost Warrior.
Panthro exclaimed:“Stronger than me? Not likely!” referring to the ‘Alien’ force,called Grune, which suddenly invaded into the Cats Lair and wrought havoc
Correct you are. Was trying for one I didn’t have to double-check the DVDs for, lol.
That’s correct Lordore and it’s your turn to try and stump us. 
OK been racking my brains, try this 1:
“..that’s no big jump for a thundercat!”
not given u much to go on but there r some pro’s here who I’m sure will get it none the less! 
Sounds like something Lion-O would have said. Maybe in Tower of Traps?
I think that’s from “Safari Joe” where Lion-O falls in a relatively shallow pit before he realizes it’s part of an ambush. :liono
Yes thats the 1! well done! lol. soz if it’s not 100% I was doing it from memory, and yes it is simlar to the safari Joe one too!
Yay, random guess. Might help that I saw that episode recently.
Okay, I had to pull out my DVD’s to find a quote…
“Frankly Lion-O, the book says no, but I never read that book.”
Oh, I can’t think of the name of the episode but I do know it’s Panthro saying that to Lion-O.
Ugh! My brain is too melted because of my restaurant design project. It’s due next Tuesday and I’ve been working on it non-stop for the past week. But one thing’s for sure, it will be a long time before I pick on Tygra again…I have a healthy new respect for him and architects. 
I’m sure this is from “The Transfer” because I saw the first part of it recently.
Lion-O asks Panthro if he can talk Cheetara and Tygra into landing the Feliner and that’s his answer.
Lady Oceli, your game has kept us on the edge of our seat!! 
I think everybody is having a lot of fun and are pretty excited with this quote game:p
In episode 49-‘‘Trapped’’
While Lion-oand Panthro are trying to navigate from the Cat’s Lair the feliner safely to the ground, Panthro says: “Frankly Lion-O, the book says no, but I never read that book.”
It is Panthro talking when trying to land the Feliner with Tygra and Cheetara, Lady Ocelli. However, Lordore is right that it is in the episode “Trapped.”
Okay Lordore, it’s your turn to try and stump us.
