\"Prime Minister Sharon was always known for his wonderful sense of humor.\" So said Labor Party Secretary-General Raanan Cohen this morning, referring to Sharon\'s offer last night for Labor to run together with Likud on one ticket in the next Knesset elections. Both Labor and Likud members were not happy with the idea. Likud Knesset faction head Ze\'ev Boim said today that the ideological gap between the two parties is unbridgeable. National Religious Party head Rabbi Yitzchak Levy said, \"Sharon had better choose very quickly whether he is headed left or right.\"
