114th base

After receiving a prophecy from the oracle of Saint Höl, you must embark on lengthy quest to find the BFG’s left testicle. After retrieving the testicle, you must climb into the BFG’s urethra to return it to its home. After the return, you need to tickle the BFG from the inside to make him cream, pushing you out of his urethra. Afterwards you will be enlightened, spreading the gospel of the big friendly giant.

“What’s three plus four?”
“114th base”

“What”

Example 2:
“What would you do for a Klondike bar?”
“Pretty much anything, but 114th base sounds like a stretch”
