"The Exploding Meatball Sub" was surprisingly a funny episode. I'm actually glad that Marshall quit his job at GNB to volunteer at the Environmental Organization because it's what he wanted. I love how Lily got tired of supporting Marshall and she almost left for Spain. I love how they ended up supporting each other in the end. The Barney plot was so silly, yet so entertaining. I love how he was angry at Marshall for leaving GNB because Marshall pointed out a stain on his shirt. I love how Barney tried to get revenge on Marshall. I give this episode a 8/10.
