“Porter, there’s a lamb in my hotel room!”/“Sir, that’s the mini baa.”

“Bar” sounds like “baa” when spoken by someone who drops the “r” sound. A joke was posted on Twitter by Ian Hall on January 13, 2015:
   
“I asked a porter why there was a lamb in my hotel room. it’s all right sir, he said, that’s just a mini-baa.”

Where does a lamb get a drink?
From a mini-baa.

If you called it a mini baa, people wd expect to find little bottles of gin inside it. Or worse, find a lamb in a hotel room.

I phoned the receptionist and asked why a lamb was running around my hotel room. Sorry, sir, she said, but that’s the mini-baa. #1PUN
