I'd just climbed into bed and snuggled under the covers when Seanie came running into the room and leapt onto the bed. He immediately snuggled up next to me, although he didn't get under the blankets since he had to run back to work. It was cold, so his hands were kept under his body for warmth and he was wiggling like a worm on a fishhook.

Me: What are you doing?
Seanie: I'm hotdogging over!!
Me: ...
Seanie continues his thrashing/shivering.
Me: Hotdogging?
Seanie: Yeah!

I consider for a few moments, but nope, I'm still lost.

Me: ...what?
Seanie: Y'know, like a hot dog. They're compressed into a tight package and they have no arms!

I burst out laughing and couldn't stop for five minutes because of the sheer ridiculousness. I mean, I think I got where he was coming from. I was "packaged" tightly into the blankets, and he was snuggled up right next to me so we were like hot dogs, I suppose. And it is true that hot dogs have no arms, and his arms were hidden under his body. But...what? When he cast about for an example of something with no arms, how did his brain land on hot dogs?

When I recovered from my fits of laughter, I asked him, "Why hot dogs?"
His response? "'Hot dog' is a very versatile word!"

That broke me again, and I was laughing so hard that I was sobbing. Seanie went back to work, pleased that he'd amused me so much before I fell asleep.
