[Airehiriel]

Gandalf (if he could ever become senile) would stand in front of doors saying "Mellon" over and over, never opening them for himself. When someone finally opens it, he thinks he has triumphed.

Biblo would search around for his dentures, and regale the staff with stories that never really happened, but how he managed to always save the day.

Frodo would stare at his missing finger all day, while mean residents teased him about being Nine Fingered Frodo. They'd call him NFFffffffffff.

Sam would go around evesdropping under all the windows just waiting for another plot.

Pippin would always complain that he hasn't eaten yet today. He'd ask if they knew about elevenses, luncheon, afternoon tea, dinner, supper. And always be frantic at the thought that they were trying to starve him. He'd probably say, "Why, I had better going through the mines of Moria!"
