That's season 7 and the episode is called "Ripped". The guy Elliot was fighting was his old partner, Pete Breslin, who was hitting his teenage son.
The chances are that they will see a cute guy and... posibly.... fight overt him. That's what might happen
They sort of fight in original episode 193.
I don't know of any big fights between them, but there is a small moment in episode 22 with Lee and Naruto, though the main fight is Lee vs Sasuke.
lee was never and hasn't ever been fat, but there was an episode where two imposters come to the hidden leaf in the form of lee and guy, and in that episode the lee imposter was fat and that episode was 161 the apperence of strange visitors.

neji doesn't fight kimimaru. lee does... in a very weird way... a sake way.... you have to watch the episode yourself... oh yea gaara is in it too..
guy only has taijutsu he has no summoning animal..exept Rock lee probably no it's Rock Lee who can only really do taijutsu. Gai summons some turtle in an episode right before the Chunin exam, when Sasuke and Rock Lee were going to fight. That's when Rock Lee shows off some move that Sasuke uses later on in the Preliminary fight.
