[Verse:] My mother was frightened by A snoopy neighbor who poked his eye Through mother's keyhole and that is why I am what I am today The man who looks through the keyholes along Broadway My job is to be alert And get the lowdown on all the dirt The dirt that gathers on Broadway's skirt For that's how I earn my pay The man who looks through the keyholes along Broadway [1st refrain:] Would you like to take a look through a keyhole? If you'd like to get the in on the latest bit of sin, have a look Life is like an open book through a keyhole If you wonder what occurs 'ere the lady gets her furs, have a look Angry people who think they're tough Start to threaten but that's a bluff They may holler but they won't stuff up their keyhole So come on and have a look through a keyhole If you'd like to get a view, view of who is cheating who, have a look [2nd refrain:] So come on and have a look through a keyhole If you want to see New York getting ready for the stork, have a look Life is like an open book through a keyhole If you want to get a load of the husband on the road, have a look Lovely ladies of ev'ry kind Think they're safe when they pull the blind I see just what is on their mind through a keyhole So come on and have a look through a keyhole If you'd really like to know how she got into the show, have a look
