During the scene of when Alec Baldwin tells both Matt Damon's character (Colin) and Mark Wahlberg's character (Dignum) that he is Dignum's new boss because Queenan is dead, Matt and Mark begin to fight over receiving information on the undercovers. Matt Damon wants the information, to which Mark beings yelling, and they start fighting. The fight gets pretty serious and people break them up. After getting broken up, you notice that Matt Damon does not have his shirt tucked into his pants, however, cutting back and forth a few more times between Wahlberg and Damon, Matt's shirt becomes tucked, and the scene ends with Matt Damon's shirt untucked once again.
