You should see episode 185 from the first season. Naruto picks up this furry little creature, called an "onbu," that attaches itself to his back and won't come off until it grows up.
In one scene, Hinata is sneaking around Naruto as he walks down the street. He stops her and asks what she wants. She mentions a rumor flying around that Naruto has a kid. Naruto shows Hinata and little critter on his back, she freaks out and faints. Naruto runs over to her and helps her up. She wakes up, sees onbu, and passes out again. The scene is really funny.
If you ever get your videos to work, I have the clip in the video gallery.
Naruto and Onbu.
By the end of the episode, the onbu has grown up and Naruto is walking back to the village as normal and finds EVERYONE with an onbu of their own (even Tsunade and Shizune). LOL! Even Akamaru and Tsunade's pig are carrying an onbu.
