Quote from Adrian Monk in Mr. Monk and the Bad Girlfriend
Lieutenant Hendrix: Simple as pie, huh? He, or, uh, she breaks the glass, reaches in, throws the lock, opens the door. Adrian Monk: Permission to speak. Lieutenant Hendrix: Permission denied. Natalie: Permission denied? Adrian Monk: Permission to speak anyway. Just say one thing real quick, and then I'll shut up. These shards of glass, they're still intact. If she came in this way, she would've stepped on them. So at least some of them would be cracked. Lieutenant Hendrix: Or maybe she stepped over 'em, right? Like this. Right? That makes sense, doesn't it? Adrian Monk: Maybe. [to Natalie] Or she had a key.
