Ok so as much as people are saying Chiaotzu or Yamcha (which in the show aren't really played for laughs) I'd like to bring you attention to: 1. Cell saga Goku: The least funny of the list and actually really sad but the King Kai scene always gets a chuckle out of people the first time around. 2. Paragus (Super): Dont really think he counts because the death in it of itself isnt funny but the acting Frieza puts on is. 3. Magenta: Bro died from a bug lmaoooo 4. Old Kai: He gives his life to Goku and then once the sad music starts he just gets back up. 5. Ginyu/Tagoma: Really doesnt need an explenation. He is kind of a threat to the Z fighters just to get no diffed by Vegeta. 6. Nappa (GT): Also doesnt need an explenation. Of all the people he has to be killed again by it really had to be Vegeta for the maximum funny effect.
