BigMac doesn't know that AJ and me
Do it in my van every Sunday.
She tells him she's at Twi's, but she doesn't go.
Still she's playin by the book and BigMac doesn't know!
Oh BigMac doesn't know!
So Don't Tell BigMac!
BigMac doesn't know!
BigMac doesn't know!
So Don't Tell BigMac!
Aj says she's out shopping,
But she's under me and I'm not stopping...
Because BigMac doesn't know!
BigMac doesn't know! (X3)
So don't tell BigMac!
BigMac doesn't know!
Don't tell BigMac!
I can't believe he's so trusting,
While I'm right behind you thrusting.
Aj's got him on the phone,
And she's trying not to moan.
It's a three-way call and he knows nothing!
BigMac doesn't know!(X3)
So don't tell BigMac!
BigMac doesn't know!(X3)
We'll put on a show!
Everyone will go!
Scotty doesn't know!(x3)
Twi's place?
Why not? It's so cool when you make that face
His front lawn, in the snow
Life is so hard because BigMac doesn't know!
We did it on his birthday...
BigMac  doesn't know!(X4)
BigMac doesn't know!
BigMac won't know!
BigMac doesn't know!
BigMac's gotta know!
Gotta tell BigMac !
Gotta tell him myself!
BigMac doesn't know! (X10)
