A gentle challenge or rejoinder to a fanciful or bullshit statement or a
tall tale. An idiom you use to tell someone that you do not believe what they have just said.
Derived from the game where you ask someone to "
pull my finger" and fart, then ask them to "pull my other finger" or "now
pull the other one".
-- Example 1 --
GUY 1:
"Yeah I drank about 20 beers but the cop couldn't tell I was drunk and let me go."
GUY 2:
"Pull the other one. I don't think so."

From Scene 1 of Monty Python and the Holy Grail:
KING ARTHUR:
Whoa there!
clop clop clop
SOLDIER #1:
Halt! Who goes there?
ARTHUR:
It is I, Arthur, son of
Uther Pendragon, from the castle of
Camelot. King of the Britons,
defeater of the Saxons, Sovereign of all England!
SOLDIER #1:
Pull the other one!
ARTHUR:
I am,... and this is my trusty servant Patsy. We have ridden the length and breadth of the land in search of knights who will join me in my court at Camelot.
I must speak with your lord and master.
SOLDIER #1:
What? Ridden on a horse?
ARTHUR:
Yes!
SOLDIER #1:
You're using coconuts!
ARTHUR:
What?
