Orange's Doctor Visit
Explanation
Explain Bear
Hey, listen up, smarty pants! The joke is that oranges are known for having a lot of vitamin C. So, the orange didn't need to go to the doctor because it already had the "medicine" it needed, vitamin C. You probably don't know what vitamin C is but it helps your body. Also, the author misspelled "vitamin" which is why the joke is so bad. Is it even a joke?
