Tristan: ROBYN, I HAVE A REALLY GOOD PUN! COME OVER HERE!
Me: [shuffles over to Tristan's room] ...Ok. What is it?
Tristan: If you don't have San Pellegrino, then you're SANS Pellegrino!!! [wide open-mouthed smile]
Me: [twisted facial expression of amusement and horror] [laughter] That's terrible.
Tristan: SANS PELLEGRINO!!
Me: I actually have Pellegrino in the fridge.
Tristan: [straight face] Fuck you...mom.
