I'm too DAMNED old and a touch grouchy to be considered "silly". It's called '"illustrating the absurd by being absurd" (BTW- one of my favorites).
It's akin to when a young kid is throwing a tantrum and the adult on scene turns around and does the same thing in front of the screaming kid. 9 times out of 10 the kid stops what they're doing and watches in amazement (I've even done it to perfect stranger's kids in stores.... Priceless).
It worked EVERY time with my kids (when they were just sprouts) when we we're out in public, but at home behind closed doors they'd just get more pi$$ed at me.... so that's a win-win in my books.
Now, shaddup and pull my finger.
Yeah, Stomper, we all get it but WE'RE to old and grumpy to stop!
Now that's just silly!
