Each time I get an Ace and an Eight, I love to play the "Dead Man's Hand,"  
I am a big fan of the old HBO Series Deadwood, which had Wild Bill featured in the first few episodes.  
When Jack McCall shot Wild Bill from behind,
legend has it that Wild Bill had a pair of Aces and Eights.
What the kicker was, nobody knows.  
My guess in the Two of Spades.
