blind

After being with his blind date all evening, the man couldn't take another minute with her. Earlier, he had secretly arranged to have a friend call him to the phone so he would have an excuse to leave if something like this happened.

When he returned to the table, he lowered his eyes, put on a grim expression and said, "I have some bad news. My grandfather just died."

"Thank heavens," his date replied. "If yours hadn't, mine would have had to!"
