(Bobby's at Willie Nelson's house; Hank has come to pick him up from 'stalking')
Bobby: Hey, dad.
Willie Nelson: Hank, Bobby's been telling me all about you. I hear you're a guitar player and that you've got a narrow urethra.
Willie Nelson: He had me autograph your guitar.
Hank: You signed my guitar?
Willie Nelson: "To my number-one fan".
