Great job! Reason being is I had those same tutorials that I used in language debates. Someone would eventually claim you couldn't do modern apps with (insert "ancient" language). So, I cited Fortran on FastCGI or COBOL on Cogs. Reactions are usually silence or serious revision to points being made.

Yours is a nice improvement. If you want to add to the prank, then maybe do a modern-style app or clone of popular one that would definitely delight people. Relatively small app to not take too much time. Offer them a link to the source in case they want to check it out. Let them find out it's Fortran on thdir own. Observe the reactions while recording the best ones. ;)
