Funny yes, from high school students no.
These actually originate from two sources so far as I see:
A 1999 contest hosted by the Washington Post
http://www.washingtonpost.com/wp-dyn/content/article/2007/0
3/16/AR2007031600738_pf.html and this book
http://books.google.com/books?id=EHsYw8RJ9swC
Why someone mixed them together and then tried to pass them
off as being written by high school students is one of
those bizarre mysteries of the Web.
I recommend searching a distinctive phrase from email
messages on snopes.com to find out if they’ve been
debunked.
e.g. “not the metaphorical lame duck” site:snopes.com in
the Google search box.
