Dexter’s Laboratory is one of the funniest cartoons one could have ever seen. The main characters of this cartoon are Dexter who is a born genius, loves to invent new things and has a lab built by himself (The lab is unknown to his parents), Dee Dee who is the elder sister of Dexter and is exactly the opposite of Dexter. She loves to enjoy her life, plays a lot and her main pass time is to play with dexter in his lab by breaking his inventions or meddling with dexter when he is in middle of his important work. Man dark is the arch rival of Dexter in his school. These two are born genius and always hate each other. Man Dark had a far more bigger lab compared to Dexter’s lab but it was destroyed by Dee Dee. This happens when Man Dark gets crush on her and asks Dexter to help him. Dexter’s parents never know what Dexter does inside his room. They are like Dee Dee. Each episode is really funny. Only the first three seasons were good. The fourth season was not good compared to the first three.
