YTP: Grover teaches about echos 

"Well, thank you." "FAAAAAAAAAAAART" D:

0:53 dun dun dun dramatic Grover

grover's echo is trolling XD

DRAMATIC LOOK!! Yes. Echo Echo is The Word

I know I need sleep, when I laugh insanely too hard at this type of video

0:53 Dramatic Grover LOL.

2:26 he has a stroke

1:36- 1:55 love this part.

I was laughing so hard at the whole numbering part!!!!!!!!!!!! Hey, after he said, "Did you hear the echo?" at 1:27, you should have put in Mario's "No."

1! 3! 2! 2! 2! 2! What da ****?! At that moment over 9000 people died of laughter

Grover should have said "Can you believe this EPIC FAIL!?"

Dramatic Grover wins it.

"Six! Six! Six! Seven!" (echoes) "Six!" LOL

2:20 I haven't laughed that hard since i watched " Link Must Die "

Heres an ECHO FAIL in the Original... Grover: Oh, Well Thank You. Echo: You're Welcome!

Before the video started, they showed a sesame street ad with Grover in it. THEY KNOW.....

Man it's been how long it's still up glad to see it is

I love this! This should have WAY more views!

Dramatic Grover had me in a fit

He just said...666 but 777 rules

The cute little word EC-EC-EC-EC CO-CO-CO!

Zombi is a Take-off of Disney's Bambi and is Spoofed with Teen Titans

@sergioelmejor1 Simple. Grover says "Thank You." and the Echo Grover Voice should have said thank you back, but INSTEAD it says "You're Welcome!" See? FAIL!

Hahaha! I did mot expect the ending! That was FUNNY!

I think it's trying to communicate.

Haha, 'dramatic Grover'! XD That was so perfect. =P

Grover: ATTTTTTTTTTTTTTTTTTACK! Echo:10!

0:53 he was lookin in my soul

HAHAHAHA!!!!! 2:44 WAS SOOOO FUNNY XD

This a classic

2:28-2:34 Grover lost his voice

6 (no echo) 6 (no echo) 6 (no echo) 7 (6)

Grover: Grover! (silence)

Grover could use a brush up on his math skills! Good poop!

Grover has serious counting problems when it comes to echoes... as far as we know...

TEENENENENENENENENENE

2:20 grover the machine gun

Grover sounds like a mix between Yoda and the bear from The Cleveland Show

Grover: 1! Echo: 2 Grover: what the ****??
