Junior: Grandpa, did you see Tom Jones' huge member bulging in his trousers? Wonder how many Viagras it takes now that he is a pensioner?
Grandpa: Probably none you idiot! You shouldn't underestimate 72-years old Welshmen that still sing 'bout Dililah and Sexbombs and move about on stage like they're 22! And it's Sir Tom to you, junior!
Junior: S'pose you're right Grandpa. Tom Jones really has one serious Sir Tom!
