I also paused it when NBC zoomed in on her tatoo and noticed that Samantha either has hairy arms or globs of hair falling off of her head and landing on those arms.The joke of this is that Samantha is no better looking than Rachel - the difference in their look is that Samantha wears more expensive clothes and makeup and had a nose job.
Clothes make-up and nose jobs are appealing characteristics to cheesy pretty boys like Adam. So appealing that he can overlook loose globs of falling hair, and whiny loooong iiiiiisland accents and most of all, his family.
