Wait a minute... upon a second glance, I do believe that this may in fact be a photo of the entire cast...
Due to my sheer boredom and lack of initiative to do anything really productive today, I have spent a little bit more time looking at this photo than is probably healthy. At any rate, I think I have located the missing Bananas!
Please direct your attention to the enhanced photo below.
I am pretty sure that that is a person under Paula there. And seeing as how white-shirt guy looks a lot like Abram, Orange-shirt guy is throwing up the 3 Amigo Shocker and is standing on the tallest piece of furniture in the room (a clear symptom of short-man's complex), I feel confident in assuming that this squished fellow is Johnny himself.
