These always amaze me:
1. Their tongues ..... Spotlessly smooth and clean (not normal) and so raw/red that it looks like the skin has been flayed off.
2. The bodily fluids and saliva!!! If I could ever muster that much I'd end up passing out from dehydration.
3. When you hear the words "don't worry I'll be gentle", bruh!, you either hightail it outta there or start silently reciting your national anthem/favourite prayer/mantra.
Just had to say it.....
