They were both good, but Born to Be Wild was the better one.
Born to be Wild: This episode was so funny. I love how in the beginning some random prospector starts talking to Spongebob about The Wild Ones, a terrible biker gang. Then Spongebob starts to freak out. There was so many good sight gags, like when Spongebob rode the scene changing bubbles to the Krusty Krab. I also like when Spongebob and Patrick try to act all cool, with their clothes, bikes, Goofy Goober underwar, and Diet Blood. Lol!!!!!
Best Frenimies: I didn't really care for this one. AT ALL. Well, kinda. I thought the plot was good, but their wasn't many funny parts. only a couple. It was mostly wierd and kinda creepy. It seemed like the movie Soylent Green to me. IDK.
Born to Be Wild: A+
Best Frienimies: c+
Overall Grade: B+
