Translation of haha in Spanish

Hi, I'm back from my vacation. It gives me pleasure to learn Spanish, because I can feel the improvement continously. I studied medicine in the University of Montpellier, a student city in France.
I'm quite tired too by now. So, if it doesn't work just drop me an email and I'll see it first thing in the morning. I wanted to add new words to the dictionary however the other issues kept me more busy than I have imagined.
How do you like comics? I have actually never read them, but for learning a new language it is a great way; but the language often is not too correct. But it has mostly more advantages than drawbacks.
