My Favorite Blonde is a 1942 American comedy film directed by Sidney Lanfield and starring Bob Hope and Madeleine Carroll.

[2] Based on a story by Melvin Frank and Norman Panama, the film is about a vaudeville performer who gets mixed up with British and German secret agents in the days just before the United States' entry into World War II.

Karen arrives to New York City from Europe by ship and escapes the clutches of enemy agents by hiding in a variety theatre.

To improve her chances of getting away and get a good cover, she charms an actor named Larry Haines, who performs a small act called "Percy" involving his penguin.

They find a place to hide at the top of Union Hall for the night, but the morning after they get on a bus headed out of the city on a sightseeing tour.

The address Karen was supposed to visit turns out to be a funeral parlor, but the Germans have beaten them to it and taken the British agent hostage.

Karen and Larry manage not to get caught though and flee the scene to a U.S. Air base nearby, where they take refuge and deliver the secret bomber plans.
