Arizona Days (1937)
Billy Workman: Say mister, are you a play actor?
Tex Malinson: Well, sorter.
Billy Workman: Well, what do you do?
Tex Malinson: Well, I play a guitar and make funny noises with my mouth.
[Professor McGill's theatrical troupe billboards bill Tex prominently]
Tex Malinson: You're layin' it on kinda thick ain't you, professor? Them are pretty big letters... do you think I can live up to all that?
Professor McGill: A mere bagatelle, my boy. With myself as impresario, your success is assured.
Claude 'Grass' Hopper: Them's mighty big words, Professor, but you know Tex, he's a cowhand. He ain't no actor.
Professor McGill: My good man, I am a thespian. To one who has trodden the boards with the immortal Booth, nothing is impossible.
