Stealth Scratching

King Obsidian here; Last night before Bob came to bed I "accidentally" shed one of my claws on the sheet where I was laying below his pillow.  Then when he asked me move to out of the way so he could get into bed, his leg slid across the claw and got scratched by it.  Maybe next time he either wont come to bed late, or he'll find someplace else to sleep seeing as I got there first.
