We got in trouble
That's how it goes
Our dungbombs caught
Filch's nose
When he left his office
We opened his files
What we found inside
It made us smile

I solemnly swear that i'm up to no good
Mischief managed

We figured out how to use it
Thanks to george
Now we get around the castle
Without using the doors
Snuck into the kitchens
Tickled a pear
Hermione would die
If she saw who worked there

I solemnly swear that i'm up to no good
Mischief managed

So we gave it to harry
'cause he needed it more
We'll always help out
A fellow gryffindor
Harry knows how to use it
Were sure that he can
If someone catches him
He'll say mischief man-aged

I solemnly swear that i'm up to no good
Mischief managed
