Bad, worse, worst and wasted.

Once there’s a time four crazy people chatted together. One said, “ I am bad!” Another said, “ I am worse! Ha ha!” The third said, “I am worst! You guys are all dumber than me! Muahaha......” The last wants to beat them all, and thought for the whole afternoon. Finally, he found the right word. He finds the other three and shouted happily, “ I am wasted! Hahahahaha..... o(^o^)o.”
