Cute Dilophosaurus

How to avoid a Dilophosaurus spitting attack:

1) Say, "Ah, no wonder you're so cute." This will confuse the Dilo, throwing it off guard for a few seconds.
2) Quickly close its jaw with one of your hands.
3) Carefully stroke its cheek with the other hand.

Warning: this may attract more Dilophosaurus from the pack, wanting to be treated in the same way.
