My dear friend Glenda told me a story about having been on a TV Talk show where there is a man who holds a HUGE clock that is tied around his neck to warn the speakers and host of how many minutes there are left until the next commercial.
Later she ran into this man at a grocery store and they were chatting and he realized she might not remember who he was (she was a regular on the show) and so he said, do you remember me, I'm (whatever his name is) from XYZ Show.
She replied, "Oh! I didn't recognise you without your clock". Well, the folks standing nearby had no idea that she'd said "clock" and one woman apparently thought she'd said a word that rhymed with that... and well, er, you can imagine the laughter the two of them collapsed into...
They were still laughing out in the parking lot 10 mins later.
Well, I laughed and laughed too!!! Still laughing....
