You don’t understand 
What it is that makes me tick 
But you wish you did 
You always second guess 
Wonder if I'll say yes 
But you just 
lose out every time 

If you only knew, what, I talked about 
When I’m with my friends just hangin’ out 
Then you’d have the inside scoop 
On what to say, what to do 
That way when you play the game 
Baby you could never lose 

Don’t you wish that you could be a Fly on the Wall 
creepy little sneaky little Fly on the Wall 
All my precious secrets, yeah 
You’d know them all 
Don’t you wish that you could be a Fly on the Wall 

You’d love to know, the things I do 
When I’m with my friends, and not with you 
You always second-guess what I did 
If there's other guys I'm flirting with 
You should know by now 

If you were my boyfriend, I’d be [bad word] to you 
If I make a promise, [bad word]  through 
Don’t you wish that you could 
See me every second of the day 
That way you would have no doubt 
That baby I would never stray 

Don’t you wish that you could be a Fly on the Wall 
creepy little sneaky little Fly on the Wall 
All my precious secrets, yeah 
You’d know them all 
Don’t you wish that you could be a Fly on the Wall 

[bad word] 
Well that will go a long the way 
You are getting misinformation 

Too much hearsay, hearsay 

And what I say is [bad word] a little closer 
And what I’m gonna say is 

Don'cha [x3] 

Don’t you wish you were a… 
Hey! 

Don’t you wish that you could be a Fly on the Wall 
creepy little sneaky little Fly on the Wall 
All my precious secrets, yeah 
You’d know them all 
Don’t you wish that you could be a Fly on the Wall
