I like Heath from Pokemon Ranger: Shadows of Almia:
"That's good jobbing leader! That Ranger has no chance of victorying!"
"Wahaha! Now, time is it for having fun times!"
And when he's trying to disguise himself as Keith over the voicemail:
"Vicemail! Vicemail! This is Hea...uh, I mean Keith! This mash-up badly is going! You are Keith's friend right? Right? Then come to Hippowdon Temple right now!" - or something along those lines.
