Query: Vonnegut's a frigging genius!!!!

I'm new to Vonnegut and this is just the 2nd one I've read, but I've made up my mind! Slaughter-house Five is hilariously perceptive.... his unique style is amazingly effective. Makes you intermittently laugh and ponder, revelling all the while in the zany and wondrous realms of Vonnegut's mind. I can't stop pushing it in other people's noses and saying "readitreaditreadit". Meanwhile, I'm scrounging up my allowance to buy more of his masterpieces.
