Mass Effect 3 with Kinect.
I love yelling at the screen. Sometimes it doesn't understand me and this happens:
Me: "James frag grenade!"
[nothing happens]
Me: "James frag grenade!"
[nothing happens]
Me: "...James frag grenade

!"
[nothing happen]
Me: "James you smurfing suck balls"
James: "I'll get right on that"
