(Billy Dean/Tim Nichols)      We started out in a double wide   Had to hang out clothes out on the line   We even had your mom and dad co-sign   We used to ride around downtown singing   Money can't buy you love when times are rough   We just kept goin' when the goin' got tough.      Can't shake us cant break us separate us   Cause we've been through it all   We're at our best when our backs against the wall.      It ain't always been a honeymoon   Sometimes it feels like we're dancin' to a different tune   That's when you and me need a little breathin' room   But when we're rockin' don't come knockin'   We want to be left alone all night long   Makin' up till it feels home sweet home.      Can't shake us cant break us separate us   Cause we've been through it all   We're at our best when our backs against the wall.      We start out with a kiss in the hall   And end up holdin' each other tight   With our backs against the wall...
