Even a cursory review of the science tells us that gays indeed are born that way.But there's an important caveat that the gay activists don't mention when trumpeting this good news.

The first raters judged targets' sexual orientations from unedited videos and from partial information extracted from the videos (e.g., video without sound for ratings of movement or sound without picture for ratings of speech).

The results: 87% of heterosexual targets and 75% of homosexual targets were accurately judged.

Sometimes it derives additional humor from the recipient taking it as a genuine compliment, either because they're dumb or because we the audience know something they do not.

The stock piece of dialogue that fits this trope goes something like: Contrast Mathematician's Answer, which is equally meaningless because it's too broad, and Suspiciously Specific Denial, where the specificity is worrisome because of everything it doesn't cover.

Simon Le Vay's research has found that the size of INAH3 in gay men mirrors that of women, while straight men's are considerably larger than both.

Gay men perform worse than straight men at certain visuospatial tasks like mental rotation and targeting while women and gay men use the same navigational strategies of nearby-landmarks.

Thus, if gay men are not feminine, there is no mechanism for them having been born that way.

If gays don't acknowledge that gay is on average more effeminate, then they can't insist that they are born that way. Adam's mannerisms matched his feminine interests: there was no difficulty telling which boy was more effeminate.

Sometimes the joke is that, even in such an incredibly narrow category, the thing being discussed isn't first.
