hi! to tell ya the truth-- it does sound like it could be a pinworm that found it's way into the beer bottle! Was it a short chubby white worm? (not a grub though)
I know at night, they can migrate out of the body (via the anus), and sometimes they can't find their way back . When I was a kid, I found some of these crawling in our bedsheets--which is when I decided to get some pinworm medicine from our drug store with my allowance money. I figured my sister had it and I probably was infected. -- Our parents made us share the same bed together.
Wouldnt you know it- that after taking the medicine, I did see dead white worms in my stools. My sister to this day has digestive, uterine, and colon issues- as well as candidas. (she also still has all her old mercury fillings in her mouth yet too)
I think she may still have pinworms-- or they did damage to her organs when they were in her.
If it wasn't a pinworm that decided to have a sip of some Corona, maybe it could have been a hatched housefly grub.
All I know is-- I wonder what the public relations folks over at Corona would say if you shared your post with them..lol!
