Stupid, Clever, or Both?

I'm doing some expert programming of a tile-based game in which tile classes have references to anonymous functions that return the proper image for that tile. I figure I might as well not duplicate these. Should I make these functions onymous or just have a picture function manager that lets me get at them easily? It would be dead simple to create onymous functions for them at runtime, but it makes me feel funny to do it.

some time ago i was walking behind a group of teenagers in the city.
the following is what i saw them say and do:
teenager1: is that our bus? run!
teenager1: *starts running to try and catch the bus before it leaves, but doesn't make it in time.
teenager2: FAIL! Garry, Garry, FAIL! You FAIL! HAHAHAHA FAIL! YOU FAIL, Garry. FAIL! EPIC FAIL!

this is an accurate representation of anybody who uses the word "fail" in a /b/tardly manner.
