If you ate too many carrots, would you turn orange?

I am not an expert in this area but just asked my boyfriend and he says it has lots of beta carotene and it can actually be very unhealthy and can cause some harm. Says it can actually cause a person to turn orange. I am going to assume that we are speaking of loads of quantity, because I do like carrots very much and can eat lots but to date I am fine and or have not turned orange. Perhaps searching the net for a more clear understanding may help.
