But who's on first?

Chuck Cedar: We're looking for somebody. Longfellow Deeds.
Murph: Wow! Is that's Deeds's first name?
Cecil Anderson: Well, if the Deeds you're referring to is Longfellow Deeds, then yes, that is Deeds's first name.
Murph: Well, I don't know Deeds's first name, maybe it's Greg.
Cecil Anderson: Maybe it's Longfellow.
Murph: Maybe. But I don't know. I know another guy named Greg. You want me to call him up?
Chuck Cedar: No! Thank you. Please. Just tell us where Deeds lives.

Mr Deeds
