The basic answer to this question is yes, but it would be a silly thing to do.
As you can read below, every Yahtzee rolled after you have already scored 50 points for your first Yatzee can be scored as a bonus worth 100 points!
So why would you want a full house?
Well, If you scored a zero in the Yahtzee box then you recieve no bonus, but you can fill in any lower boz that is not yet filled.
Read on to see how Billy is actually wrong.
Yahtzee
A Yahtzee is a 5 of a Kind (i.e. all the die faces are the same), and it scores 50 points. If you roll more than one Yahtzee in a single game, you will earn a 100 point bonus for each additional Yahtzee roll, provided that you have already scored a 50 in the Yahtzee category. If you have not scored in the Yahtzee category, you will not receive a bonus. If you have scored a zero in the Yahtzee category, you cannot receive any bonuses during the current game.
You can also use subsequent Yahtzee's as jokers in the lower scores section, provided the following criteria have been satisfied:
1. You have scored a zero or 50 in the Yahtzee category.
2. You have filled the corresponding category in the upper scores section. For example, if you have rolled:
the Fives category must also be filled.
If this is the case, you can use the Yahtzee as a joker to fill in any lower scores category. You score the category as normal. Thus for the Small Straight, Large Straight, and Full House categories, you would score 30, 40, and 25 points respectively. For the 3 of a Kind, 4 of a Kind, and Chance categories, you would score the total of the die face.

So, Technically Billy is wrong.
Why? Because five 5's are not a full house but is treated as a yahtzee. You can use this roll as a joker (which is not a full house) but you are able to fill in the full house box.
