is it cheating if she only has one leg?

It's 4am and I've been kicked awake by my super awesome ninja baby, who, sadly, is insensitive to things like time. So i'm up. i've got a glass of milk and i'm pondering the profound questions posed to us in the latter half of Season 4: The Sopranos. For example. does Tony consider it cheating when he has sex with the one-legged occupational therapist known as Svitlana? And moreover, does Svitlana?

The C-man exclaims "poor Richard" (or whatever Svitlana's boyfriend's name is) and I say "no harm, no foul". It's not like he's ever going to know and Svitlana certainly isn't dumping boyfriend for Tony - she's way to smart for that nonsense. So there is no "poor Richard".

C-man says I had better adjust my definition of cheating to include all extra curricular sexual activities with other people, including one-legged persons. Apparently, Svitlana does not get a pass. So for all you one-legged hustlers out there looking to lead me away from my man, I'm sorry. We can never be together.
