They Might Be Giants
No!
No is no
No is always no
If they say no, it means a thousand times no

No plus no equals no
All nos lead to no no no

Finger pointing, eyebrows low
Mouth in the shape of the letter O

Pardon me -- No!
Excuse me -- No!
May I stay?
Can I go?
No, no, no

Do this -- No!
Don't do that -- No!
Sit, stay, roll over
No, no, no

Finger pointing, eyebrows low
Mouth in the shape of the letter O
Red means stop. Do not go
No, no, no
