If you're feeling a bit puerile and you've got plenty of time on your hands, then there are a few "name games" you can play to make FFVII mildly amusing in a pathetically shallow way.

Many people know of the joy that can be had in FFVIII by giving Griever the name "My Butt" or some equivalent. The same holds true for FFVII. Some conversations become thoroughly droll if you (in)appropriately re-name a character.

For example, when you name Barret, call him "T". Then, when he and Aeris are escaping the Shinra building, the following conversation will ensue.

Aeris: "Thank you, Mr T!"

Barret: "Who you callin' Mr T? That don't sound right!"

Giving every character the same name can lead to some intersting confusion. For example, call everyone "Holy s**t" - uncensored, of course. Every time the characters call out the name of one of their friends, they'll yell a surprised profanity. Like the scene near the beginning when Cloud flips into the train. Biggs, Wedge, Jessie and Barret eachl yell "Cloud!" "Cloud!" "Cloud.." and "Oh, Cloud", or something along those lines.

Anyone else have any ideas for potentially amusing character re-names?
