If I have to pick from laugh/cry/swoon, I think the first book I remember really affecting me that way was in how hard I laughed at Douglas Adams' "The Hitchhiker's Guide to the Galaxy." I laughed out loud constantly when reading it and usually at highly inappropriate times, and it definitely influenced my development as a writer and the sense of humor I think I still have today. I'm not longer trying to emulate Douglas Adams in my writing (my first book actually has several passages that looking back make me cringe a little in how alike they are to his style) but it was definitely a formative work for me!
