The 23rd letter of the alphabet, pronounced "Double-You". When in fact it should be redefined as "Double-Vee" because it does not in fact look at all like 2 U's (UU) but looks more like 2 V's (VV), thus why it should be redefined.
Teacher: What is the 23rd letter of the alphabet?
Kid with brains: Double-vee
Teacher: I'm sorry, that is incorrect, the answer was Double-you
Kid with brains: Listen bitch, I was correct, when you write "double-you" do you put 2 U's together? I think not, do you join to V's together though? I think so. So shut your face, I'm rick james bitch!
