OK, here's the joke:
I'm 50 pounds overweight... about 22Kg.
So I got teased about whether I'm pregnant.
I answered "yes, it's going to be an Elephant, we've seen the trunk already".
So that's why you being an Elephant should "be taken upstairs" (to the bedrooms) and not shown/done here in the tavern.
*sigh* Yes, English jokes twist the sounds of words, and sight-pictures.
12B4, but that's another nonsense thread.
