What is that?

An old Jewish man was finally allowed to leave the Soviet Union, to emigrate to Israel. When he was searched at the Moscow airport, the customs official found a bust of Lenin.

Customs: What is that?
Old man: What is that? What is that?! Don't say "What is that?" say "Who is that?" That is Lenin! The genius who thought up this worker's paradise!
The official laughed and let the old man through.
The old man arrived at Tel Aviv airport, where an Israeli customs official found the bust of Lenin.
Customs: What is that?
Old man: What is that? What is that?! Don't say "What is that?" say "Who is that?" That is Lenin! The sonofabitch! I will put him on display in my toilet for all the years he prevented an old man from coming home.
The official laughed and let him through.
When he arrived at his family's house in Jerusalem, his grandson saw him unpack the bust.
Grandson: Who is that?
Old man: Who is that? Who is that?! Don't say "Who is that?" say "What is that?" That, my child, is eight pounds of gold!
