Sam & Becky are celebrating their 50th wedding anniversary and Sam says to Becky "So, Becky, I was wondering... Have you ever cheated on me?"

"Yes, Becky, I really want to know. Please..."
"Well, all right, 3 times"
"3, hmmm, well when were they?"
"Well, Sam, remember when you were 35 years old and you really wanted to start the business on your own and no bank would give you a loan. Remember, then one day the bank president himself came over the house and signed the loan papers, no questions asked... Well..."
"Oh, Becky, you did that for me! I respect you even more than ever, to do such a thing for me. So when was number 2?"
"Well, Sam, remember when you had that last heart attack and you were needing that very tricky operation, and no surgeon wanted to touch you. Then remember how Dr. DeBakey came all the way up here to do the surgery himself and then you were in good shape again... Well...."
"Oh my God! Becky, you should do such a thing for me, to save my life... I couldn’t have a more wonderful wife. To do such a thing, you must really love me darling. I couldn’t be more moved... So, all right then, when was number 3?"
"Well, Sam, remember a few years ago, when you really wanted to be president of the congregation.... And you were 47 votes short...."
