There's no other Finnish dialogue in the scene that could enrich the one-liner. The other character, Helena (Mari Rantasila), doesn't say anything. Kaurismäki is certainly capable of a subtitle joke ... especially since he knew a film with this title would find an English audience.

Always made me wonder, whether Kaurismäki introduced Hamlet in this way just for the subtitle joke - and even whether this Hamlet's gluttony was initially conceived for this joke.

The subtitle translation is by Mikko Lyytikäinen (from the new Finnish Futurefilm blu-ray), but it's quasi-identical on the older Artificial-Eye DVD.
