One Trick Mind

Overheard on the subway. Two coworkers were speaking about a third coworker whom they seemed to not think highly of. While some might say this is a malaprop (“trick” for “track”), I think it is a bonafide malaphor, mixing “one track mind” (hyper-focused) and “one trick pony” (having limited skills). A shout out to regular malaphor contributor Verbatim for sharing this one!
