Transubstantiation. Budum tshhh Thank you, I'll be here all week.
No seriously, I don't know sorry.
So, this might not be in the vein you're thinking of, but the structure of talks that Mormons give pretty much always starts with a story that ends in a punchline before the real meat of the talk begins. So much so that when I prepared my own I followed that format to get laughs before talking about whatever topic it was I was assigned.
