We temporarily lived in an apartment that faced a courtyard. Every night around 2am, the "Screamer" would get going - she sounded like a bad porn star. The first one or two episodes, we could not stop laughing - we thought it was absolutely hilarious. After that, it got seriously annoying... to the point that we moved out. Who the hell wants to hear that every night? It's really inconsiderate to neighbors, especially considering there could be little kids living nearby.

Sorry you have to deal with that - I have no good advice, other than maybe knocking on their door the next day and diplomatically informing them that you can hear their events in more detail than they might realize.
