Stupid State Laws - Pennsylvania 2

Here comes another post about a state law that still exists on the books and why it is ridiculous (to see them all, click here):

Pennsylvania

"It is illegal to have over 16 women live in a house together because that constitutes a brothel.  However up to 120 men can live together, without breaking the law."

The first part of this law makes perfect sense other than the fact that it means all sorority houses in the state are nothing but large whore houses (and with hot young chicks to boot), but the second part is a little confusing.  Does allowing 120 dudes to live in a house promote male brothels?  Or does it mean that they are okay with letting a ton of Mexicans live in the same house?  Or do they have a lot of clown colleges in the state and because clowns are good at packing themselves into cars, the same principle applies for houses?  And for that matter, why is the number 120 so specific?  Does that mean that 121 dudes can't live in the same house?  Answer me these questions, Pennsylvania!  Answer me, dammit!
