Name of movie where young tour guide takes people in apartment building and they all breathe together ?

Question

I saw a comedy movie AGES ago where, I believe, the young lead acts as a tour guide (maybe in NYC) and takes his customers into an apartment building and tells them to breathe in the atmosphere (or something like that). They all are taking deep breaths in unison on the stairway and alarm an apartment dweller who opens her door.

Answer 1

Is it "Joe's Apartment?"
