Hm, I never though of it that way! :D I was going to say (and decided against it, because I fear his reaction! :T) was that he is cute when he's mad...
Yes, of course I do! It's what you get when someone scares the bejesus out of you *yes, I know, not covering every scenario you get an adrenaline rush from*. I mean WHY did you have an adrenaline rush?
One time, it took me a minute to eat, and my sister totally freaked. She's like, "You're done already?! Man, that means I have to let you in!" We "share" a bedroom. She hogs it the whole day. XD
If you look up "Impmon" and go onto the Digimon Wiki, you will find basically everything that has happened in his life up to this point! STALKER WIKI PEOPLE!!! (Also, it states that Impmon "scarfed down as much food as he could" at Rika's Bday... Hmmmm... Yep, sounds like Impy to me! XD)
