Back in the day that would have been part of St. George's colon ...at least it hasn't farted in that jar...
Looks like someone squished together a bunch of chewing gum + toilet paper and threw it into a jar full of apple juice. I'm going to become an alien organ distributor now.
Just out of a bit of fun i looked for Veritas laboratories incorporated, as in the letter, and it seems to be very hard to nail down on who and what they are, i have found a Veritas laboratories which deal with medical matters, but it is not "incorporated", so it can't be that one.....and i love the letter head "To whom it may concern", no name, nothing. lol Of course it also does not help their case that in one of their ebay pic's their search history on ebay shows aliens in jars. lol Call me Susan and slap me with a wet fish if this is not 100% grade A, triple gold star rubbish. lol
I mean it's fairly obvious that's a jar of water with jizz in it, like the cum box story. Also lol, lets get some random strange looking plant and jam it in some fluid.
