You're out having lots of fun and you're not hurting anyone
But when someone says "that can't be done"
That's a fun detector
Fun detector, fun detector, lower your brow and raise your finger
All these people are having fun
Something must be done
The mirth monitor's on a raid
Thinks they oughta be obeyed
Come to rain on your parade
That's a fun detector
Someone's trembling at the lip
Their about to let it rip
Going on a power trip
That's a fun detector
You're a wet blanket
You must have been dropped on your head
And you mustn't have been breastfed
