Simba was walking too slow so I told him to Mufasa.
Simba and Mufasa Pun
Explanation
Explain Bear
Listen up, you chucklehead! This joke is a play on words. Simba's dad is Mufasa. The person telling the joke is telling Simba to "move faster", but it sounds like "Mufasa". Get it? You probably don't because you are not smart.

You misspelled “Mufasa”. That ruins the joke.
