Coat Tree?

I was recently reminded of an event that took place a couple of years ago. My sister Trixie, her husband the Coonster, Art and I go to the coast once a year. It is an event that Art and I look forward to and it is always a fun adventure. Well a few years ago we were at Chinook Winds and Trixie and the Coonster took a bathroom break and Art and I stood outside the facilities and waited. While we were standing there, Trixie came out and said to us "there is a code three in the bathroom come and check it out". She and I then went in to the bathroom to find a woman in her mid nineties with her seventy five year old daughter. The eldest woman was experiencing some problems which required some medical attention. Immediately after we got in the bathroom, security arrived with the paramedics requiring Trixie and I to retreat to the other end of the bathroom and wait to make our escape. There was quite a commotion. After about ten minutes we were able to walk out.

The Coonster was very upset and concerned that something had happened to Trixie and that was why the paramedics had arrived. He had reason to be concerned as not long before our trip, Trixie had suffered a stroke (she has recovered and is doing well). He tried to get in to check on Trixie but security wouldn't let him. You can imagine his worry. I couldn't understand why Art didn't tell him what was going on. He stood right next to me when Trixie said there was a code three and he knew she was O.K. and yet he seemed concerned as well. Here is our conversation.

Me: Why on earth did you let the Coonster get so worried? Why didn't you tell him what was going on?
Art: I didn't know what was going on. They wouldn't let us in to see if Trixie was O.K.
Me:You knew it wasn't Trixie
Art (looking very surprised)I wasn't in there, how did I know it wasn't Trixie?
Me:because you were right there when she came out and said there is a code three in the bathroom come and check it out.
Art: Code Three?!?! I thought she said there was a coat tree in the bathroom come check it out, and I thought that must be one hell of a coat tree.

Oh dear.....
We all had a good laugh. In fact, just thinking of it makes me chuckle.
