I took it to mean that the person referred to is an opportunist of sorts. A man who will perform said act on another man for some kind of benefit, despite being straight or disliking that man.

That was pretty funny..safe travels indeed.

George Carlin (who is idolized and rightly so, mostly) had a line in one of his standup specials where he said “you show me a tropical fruit and I’ll show you a cocksucker from Guatemala”. Homophobia was just so normalized back then (this was the ‘80s).

I don't think this bit was homophobic at all, and that you've misinterpreted it, through omission and otherwise. If anything, homophobia is part of what is being laughed at (and a small piece of the overall joke). I'll explain.

To begin with, you left out key parts of the joke; he wasn't expressing that as himself. Here's the full bit:

I remember something my third grade teacher used to say. She used to say "You show me a tropical fruit, and I'll show you a cocksucker from Guatemala." No, wait... that wasn't her. That was a guy I met in the Army.

While the joke uses "fruit" as slang for gay as part of it, that isn't actually even the punchline, the wordplay is just a vehicle for it. The humor primarily hinges on the notion of a grade school teacher saying something that crass (the second part specifically) to a child, coupled with the implication that it was something she said more than once ("used to say" instead of "said").

Then he realizes it was some grunt who was in the Army with him (who it'd make more sense to say something crass/uncouth like that), which adds another element of humor in 'how could he possibly mix those two people up?'. If anything, that hypothetical Army guy is being laughed at in part for the homophobic slur usage.

Yep! And that's part of the culture I grew up in and came to age in. Media that demonized and mocked gay men (and really all gay people), even otherwise progressive and lighthearted media.

It was damaging to me as a child. More so than a lot of people could ever realize.

Also disheartening is that a lot of my super religious family will use the term cocksucker as a derogatory statement right in front of me, knowing I'm gay. These are the same exact people who literally freak out and act like you've shot their mother in front of them if you say the word "fuck" or "god damn".

Why two or more?

Do you think people with only one child no longer have sex?

Growing up, the worst thing you could be was a guy who liked other dudes. Being called a fag and cocksucker was just like "casual" insults, the way Australians call someone a cunt.

I kind of like when it's reclaimed. Like someone calling themselves a fag or a whore.

Because usually the bully ends up getting even more mad.

interestingly, it's less about flexibility and more about 'strength.' There was a how-to guide a while ago that emphasized the method of 'hands behind thighs' to pull oneself to that point. Leverage and body mechanics make it pretty difficult, and flexibility isn't even half of the battle.

All over Deadwood.

But being called a Cocksucker by a wild West brothel owner may be historically accurate.

Sopranos is pretty funny I guess
