I like the fight in Ultimate X-men volume 2 where Wolverien and Sabertooth are fighting in the snow (Sabertooth just got claws put in to his hands to be like Wolvie, except he had a total of eight). Wolverine ends the fight by stabbing Sabertooth in the crotch and tackling him off of a cliff. That was hilarious.
Also later tin that series when, Sabertooth is bragging about how much better he is than Wolverine and Wolverine just walks right up to him and slices his head off.....
