It's the one where Keiko and Miles O'Brien (almost don't) get married. But we're getting a little off topic.
I took a quick peek at the Wikipedia page for camels and it turns out that, despite them being mammals, their body temperatures fluctuate pretty wildly depending on their environment. At night, they're often cooler than humans, and during the day, they're often hotter. Another click to the body temperature article told me that lower body temperatures often mean that a mammal is slightly longer-lived.
Extrapolating this out to Vulcans, who are presumably desert-adapted mammals, it seems that it would make more scientific sense for them to be somewhat cooler than humans under most circumstances -- but definitely not all (and a love scene would qualify as an exception given that our own body temperatures rise when that's going on). It'd also partially explain their longer life spans.
This being said, this is science
fiction where, if it comes down to plot vs. accuracy, plot's gonna win every time. I tend to be a bit agnostic on the issue of whether or not Vulcans are warmer than humans; it seems the only safe assumption is that the body temperatures likely aren't going to be the same.
