Search Results: guys become annoying

When I was a little kid, I vaguely remember a scene from a movie, but I can't remember much. I think it was a comedy.

General Setting:
An urban city (likely in Europe).

Characters:
Some random guy
An annoying fly

General Plot (or what I remember from it):

A guy is being plagued by an annoying fly that he can't seem to get rid of. It's actually far worse than the fly in the Mr. Bean show. He tries many times and keeps failing constantly.

In one memorable moment, the guy wears a trench coat carrying a lot of pesticide spray cans and goes into a phone booth. Of course, the fly followed him into the booth, so he tried to spray it, and kept spraying until the entire booth became completely obscured by a mist of pesticide inside. He falls outside of the booth coughing violently. Of course, the fly just flew out completely unharmed. The next scene, he's in an oxygen chamber in a hospital.

The other thing I remember, is that near the end, he sets up a lot of traps in his home, making the place look like a big Rube Goldberg machine. Every trap fails, and as he lies in the ruins of what was once his home, the fly lands near him. The fly triggers the movement of a glass ball that rolls off a ramp, and falling on top of it, killing the fly instantly.

The man, beat up and tired, just starts to laugh hysterically.

That's all I remember. Anyone out there know what this movie might be called?
