What makes Melissa McCarthy funny? It's not just the lines she improvises or her delivery of those written for her, it's her fearlessness.

And it's all for the sake of your genuine enjoyment. If you don't believe us, you will soon. Here are GIFs to convince you that Melissa McCarthy is the funniest woman in comedy right now
