which of these has the make up and "stuff" to be a starter, and which is better suited to the bullpen?

I'm guessing the sour puss on the left could easily give you 8 plus innings of 'tude, while the one in the back prefers to work in short bursts when he / she can be bothered to work at all.

I'm trying to figure which one of them looks more like Jamie Hyneman from "MythBusters"

Looks like Blofeld's cat and a buddy.

The sour puss on the left is a LADY! Tashi. The Ding-Dong on the right is Moseph, aka Moe Green, and he's a little over a year. Guy is a total fraidy cat clown. I call him Liberace cause my wife is turning him into a puffy fruitcake. Tashi is a lover, the most affectionate cat I've ever had. She could be a closer. Mo doesn't play baseball but would be a great hockey player.

Now them's a couple of punums.

Adorable!!!

[4] heh.. you know I knew the one on the left was a lady (didn't even have to ask) - but the one on the right could go either way. Moseph Liberace, that's rich!
