I always thought the mental image associated with Rebuke Undead was kind of awesomely hilarious.
"NO! Bad skeleton! No! We do that on the GOBLINS, not on me." *whaps it with a newspaper* "GOB-LINS." *gestures emphatically* "Bad skeleton! The God of Death is VERY unhappy with you right now."

Oh and I'd trade 5 feet feet for the buff to channel divinity powers at level 11 that the cleric gets.
