'I don't like it... I love it!' is perfect when my daughter shows me one of the two thousand things she's made in ceramics class, for example. But I think she knows where I got it.
I also use "You _________-dummy" whenever possible. Trying to get the whole "crack a _______ book much?" is too difficult in most circumstances.
Once I was at a weird and somewhat awkward gathering of two hippies, two of their friends, and my friend, trying to make conversation, or at least fill in the extended silences. Luckily I had my iPod with me and I randomly played tracks from the SXSW 2010 preview download saying in my best DJ voice: "Hey guys... how 'bout this track: SMASH OR TRASH?!"
I know it's not a joke, and in the end, after the tenth song, it was becoming clear to me that it was irritating as well.
So I stopped.
