Petras coming back kind of reminds me of Roger's riddle off of Training Day:
Roger: "One day this man walks out of his house to go to work. He sees this snail on his porch. So he picks it up and chucks it over his roof, into the back yard. Snail bounces off a rock, cracks its shell all to shit and lands in the grass. Snail lies there dying."
Roger: "But it doesn't die. It eats some grass. Slowly heals. grows a new shell. And after a while it can crawl again. One day the snail up and heads back to the front of the house. Finally, after a year, the little guy crawls back on the porch. Right then, the man walks out to go to work and sees this snail again. So he says to it, "what the F's your problem?"
Or the Rocky Doll:
“You can kick it, you can beat it, takes a great beating”.
I thought for sure Petras would head for the hills after this past year and his warm receptions during the Kinnick home games.
