Place it at the start of a scene where a character takes charge, with Sudden Suspense just before it to build tension, then follow the welcome with Silence I Kill You as the next line in the interrogation.
Über diesen Sound
This two-second voice clip is a single Bulgarian line in which a speaker welcomes the boss to state security, using the formal language of an official arrival. It feels mock-serious and slightly menacing, turning an ordinary entrance into something that sounds like a checkpoint or an interrogation. The humour comes from that contrast between a polite welcome and secret-police formality.
