Grimmjow never saw the roundhouse kick that hit him squarely in the face. Wham.

"Why are you home so late? Were you out with a girl! My son has finally become a man! I'm so happy I could-"

The hall light was snapped on by a grouchy and barely-awake Karin, revealing Kurosaki Isshin throttling the life out of one Grimmjow Jaegerjaquez, would-be assassin.

"...You're not Ichigo."

Meh, I don't think this is the best that I've written, but I found it in an old notepad and thought it was reasonably funny ^^
