Bertha Puns

I was at church with my father who is the pastor, so lots of people come up to him weekly. I went to go say hi to him after church, and an older lady by the name of Bertha comes up to us and introduces herself. After I tell her my name, she asks me if I play football. I shake my head and give her a puzzled look and she says, "oh well you have a strong looking body". Of course I get rather excited about this and say, "dad did you hear that, she thinks I play football?" He responds with, "son, we've been praying for Ms. Bertha's eyesight for a long time now"
