Quote from : How to Train Your Dragon 2 Movie

Hiccup: [playing with Toothless] He's down! Ah, and it's ugly! Dragons and Vikings, enemies again, locked in combat to the bitter...
[Toothless pins Hiccup, who moans in mock pain. Toothless then licks him repeatedly]
Hiccup: Ugh! C'mon!
[jumps to his feet and wipes the drool off his clothes]
Hiccup: You KNOW that doesn't wash out!
[Toothless laughs and Hiccup playfully flicks the excess drool at him]
