Leuenberger (sp?)

So just for fun, I wrote this bonus question on my freshmen science class's test: "Spell Mr. L.'s last name."  I expected many misspellings, obviously.  What I DID NOT expect, however, was the wide variety that they came in!  I had FORTY different spellings of my last name!  They are as follows:
