Since 1992, when "The Real World" made its historic debut on MTV, we've watched an unforgettable batch of cast members leave their comfort zones, journey to a new city (and sometimes a new country), and reside with six strangers in some luxurious pads. During their three-month stints away from home, the group of young adults stopped being polite and started getting real -- and thanks to their poignant conversations and sometimes unbelievable antics, we've witnessed a mountain of memorable moments (look no further than the trio featured above).

In honor of the milestone 30th installment, "Real World: Skeletons," premiering on Tuesday, we're taking a fond look back at 14 incidents from Season 11-20 -- Chicago, Las Vegas, Paris, San Diego, Philadelphia, Austin, Key West, Denver, Sydney and Hollywood -- that are simply impossible to forget:
