Funny things at work

An amusing incident from work...
Betsy was talking about some liberal radio story, ranting on.
Jokingly I said, "Poppycock!"
She said, "What?"
(I should at this point mention that Betsy is somewhat hard of hearing)
I said, "Poppycock!"
She said, "What??"
I said, "POPPYCOCK!"
She said, "Poppy what?"
At this point I was laughing so hard that I could hardly get out the word, "COCK!"
And then she said, "Oh. I've never heard that word before."
