The window-licker in question is W. Kristoph Nolen, a top-notch drinking buddy and very talented artist (and apparently a skilled photobomber as well!).
Bwah-ha-hah! This is great!
I thought they'd snap another one when I was being silly and photobombed this one! A great pic ... lots of fun was had by all. This will be a fond memory for me. :)
"Licking the window like a cat ..." LOLOLOLOL!!!!
