This episode was hilarous! Another episode with Jerry's parents... and they are one of my favorite recurring cast members! This episode was so funny, as you didn't know what was goanna happen next and you also had no clue to how it was going to be solved.
"Who figures an immigratant's goanna have a pony?"
That line, which Jerry repeats throughout the episode is also funny ;)
I also love at the end how the game is posponed, you think everything is goanna work out OK, but then Jerry gets kicked off the team! It turns out that episode turned out no good for anyone!
Good job to the writers and actors on this one :D
