I was actually training a collections/customer service agent who turned out to be the dumbest, yet funniest person ever.
We went through the script, and he was fine. When it came time to give him his first call, this is what he said, no joke...
"Hello, my name is , what can I help you with tod...aw shit!" Instead of saying his name, he said blank, then swore while the customer was on the phone. Needless to say, the customer understood and we all had a good laugh.
