I have never been a fan of combat magic; the act of hurling balls of exploding flame quickly becomes dull. I love playing magic-users because of the utility magic, the stuff you use outside of killing your foes and taking their stuff. If you want something dead, use a sword. 
I want to know what your favorite utility magic is, and why. It can be in any form: spell, ritual (if 4E is your thing), or magic item. Feel free to share any interesting stories as to why you like the particular utility magic. The only rule to this game is that the spell should have nothing to do with killing stuff.
I'll get the ball rolling. Tenser's Floating Disk is one of my favorite spells, one every mage I run has memorized at least once. Whether it be hauling loot from a dungeon, or 30 pounds worth of eggs to throw at someones house (we did this to an evil mayor), Tenser's Floating Disk does the job.
