There is an incident in the Avodah Zarah tractate concerning a blasphemous joke Rabbi Eliazer overheard and derived pleasure from. This sin, according to the Rabbi himself, resulted in his wife and daughter being sold into prostitution. The thing is, the joke is pretty funny. Is its inclusion in the Talmud not a sort of "stumbling block before the blind", laying in wait for poor Yeshiva students? I myself have been unable to go more than two weeks without thinking about the joke and having a good laugh since I first read it.
I think the point in those sugyas is that it was untenable for such a tragedy to befall a completely righteous person. So reasons were offered to justify their intense torture. Pronouncing the ineffable name even in a situation where it is allowed, taking pleasure in a min's words etc.
But these are things that very much lifnim mishuras hadin, applicable when Hashem treats his close ones extremely strictly.
Common folks don't get punished for these things. We get punished for the real sins we do. And I assume most people who are on the level to get punished for these types of sins wouldn't get pleasure from that line, considering it's source.
