I'm surprised you didn't mention Reservoir Dogs (still my favourite Tarantino film). Then again, there is nothing funny about any of the violence. Perhaps that's one reason why it's still my favourite, as the genuinely horrible violence stands in stark contrast to the humour elsewhere in the film. I do think Pulp Fiction is a masterpiece too. The rest of Tarantino's output I can take or leave (though I did enjoy Inglorious Basterds and Django, despite the glaring flaws in both).
