Popeye the Sailor is very old cartoon. Here Popeye is the main character with Bluto being his arch rival in it. They both try to impress Olive Oyl who eventually falls for Popeye in the end as Bluto tries to get her by behaving badly. He all the time forces her to like him. He is stronger than Popeye. But Popeye gets strong only if he takes spinach. It makes him the strongest. Small kids started liking this cartoon and many were inspired to eat spinach after seeing this. I also heard that the spinach sales raised after this cartoon was aired as it inspired many kids. I love this cartoon a lot.
