Running off at the mouth

Get me a job as a mime Help me get out of this rut I need something that helps me To keep this big ol' mouth shut I don't think before words fall Oft' don't hear them for myself Sometimes I think I should be Stuffed and set upon a shelf Sometimes I make people laugh Other times I make them cry Not thinking before I speak And too slow to even try Can even amaze myself With the stupid things I say And I hear the echoes loud That just will not go away I can talk to anyone Well, I even talk to me And what makes it so much worse I rarely make apologies
