Gotta Be This Or That

If you ain't wrong, you're right
If it ain't day, it's night
If you ain't sure, you might

If it ain't dry, it's wet
If you ain't got, you get
If it ain't gross, it's net

If it ain't sis, you can't miss
It's got to be your brother
Can't you see it's gotta be
One way or the other?

If it ain't full, it's blank
If you don't spend, you bank
If it ain't Dee, it's Frank
