I felt that the pairing in this episode was stellar. To those who are saying that it was unrealistic, I say that at 21, I was going to bear bars and hanging out with gay men of many ages - my own and also older.
The gay life of a 40 year old is no less relevant than that of a 20 year old. In many ways, it is MORE relevant, because at 20, we don't know nearly as much as we will later in life. I've seen this demonstrated over and over.
As for the assertion that the young ones didn't deserve to be taken to task for taking their shirts off - I disagree. They knew what they were doing; they knew that they weren't gay and were therefore misrepresenting themselves. For thatn alone, they deserved the harsh words.
