Tony's Chicago Cubs coffee mug is one of the only props to stay on the set after the bomb blast that took place at the conclusion of the previous episode. This wasn't a conscious plan - in fact, it was initially marked for destruction. A crew member tossed the mug into the air to shatter it on impact, but it got stuck in some overhead lighting. After it was retrieved, a collective decision was made that the mug was indestructible. Tony is seen sipping from it even much later in the series.
Reiko Aylesworth, Michelle Forbes, John Terry, and Jon Gries were all on the TV series Lost.
