No need to sulk, allo, that was a male allosaurus. I'm sure the weaker of the sexes . . . .
Change "Rowr" to "Rawr" in the flirting situation, and everything's fine.
Give a male Allo a chance at battling a determined Camarasaurus, and... Well....That won't go as well as the flirting situation.
And if Al was changed to Alexandra (*ahem* FEMALE!) then Bob would have the pizza to himself. Fe-Allos will go for the steak.

edit: Yah, there's some signature non-understandable Allosaurus humor.
