I can understand why a lot of people don't like Timon but I personally love him. Like Moka said he can be a jerk but he knows who he loves and he's loyal to them. I personally love how he makes everything into a joke... he reminds me of... well me XD
Now Pumbaa... he's just a big lovable ball of meat and potatoes...
He's a sweetheart and both of them together make a great pair of friends.
