Much like sulfur, I find minor skunking can dissipate. I've made a farty beer before (many years ago) where I recall telling my friends "pour it into your glass, then walk away for 5 minutes, then come back and enjoy". Mercaptan compounds are of course volatile so it makes sense to me that in some cases you could do the same thing to a slightly skunked beer -- pour, walk away, come back and enjoy. Or, just embrace the skunk.
