In the episode the Jerusalem duality from the series the big bang theory sheldon sings aye aye aye aye hava nagila they'll come they'll settle and I'll win the prize does anyone know the song?
It's amazing isn't it!
Basically, Hava Nagila is a Jewish folk song, which Sheldon modified to say he'll "win the [nobel peace] prize".
Good answer but the song is not a modified vesion of "Hava Nagila", It's actually a Mexican (?) song called Cielito Lindo, with the lyrics changed to say he'll "win the prize"
The Third Crusade's resulted in a failure to recapture Jerusalem. Saladin still had control, but there was a treaty made between Saladin with Richard the Lionheart for anyone to be allowed to visit the holy land of Jerusalem. It resulted in the capture of the cities of Acre and Jaffa. The crusaders however failed to recapture Jerusalem. Saladin was forced to sign a treaty which guaranteed safe passage to Jerusalem for unarmed traders and pilgrims.
It is actually unclear what the name Jerusalem means. The closest anyone has been able to come is "City of Peace", but it is unclear if this is accurate. In terms of what Jerusalem is, it is the capital of Israel and the de jure capital of the Palestinian Authority and the site of numerous holy sites for all three monotheistic faiths.
