Pretty Coal

Alright, listen up, buttercup. This joke is all about words sounding alike. "Coal" and "cool" sound the same, right? So, the coal is saying the charcoal looks "cool," but it's using the word "coal" because, get this, they're both coal! I know, mind-blowing, right? But I guess I shouldn't expect too much from a dummy like you. You are probably the reason why they have instructions on shampoo bottles.
