pm: our client wants a proprietary pdf compression app.
me: Okay gimme 3 days and some sample PDFs.
pm: they won't supply any sample PDFs because they contain confidential information.
me: okay fine, I'll download some from the interwebs.

** 3 days later **

me: here is the pdf compression app. all done and works with all of about 100 PDFs we tested with.
pm: okay great I'll have the client take a look.

** half and hour later **

pm: the client said that the compression app errors out.
me: okay I'll go look at the server logs to see what's up.

** 10 seconds later **

me: what the shit is a "foxit phantompdf" file.
pm: it's the proprietary pdf format that they are using.
me: oh joy. I'll go try to find some sample files and see if I can fix it.

** 1 hour later, no sample files found **

pm: got anything?
me: *sobs obnoxiously*
