For the sake of the possibly of making him a bit more happy than he already is, I fully agree with Mister AL.
I mean, I see no reason why anyone should be excluded from the right to get married, nor do I see a reason to limit the number of persons in marriage regardless of skincolour, gender and grade of underarm perspiration. Until everybody is married to each other, and we're all one big clan, if you want.
But seriously, why? To feel special?
