HTL 

HTL is the acronym for HÖHERE TECHNISCHE LEHRANSTALT and it's the type of school no one wants to visit but a few people in Austria (about 50,000) do it anyways. If you are a HTL student you may suffer from depression or become an alcoholic. The main tasks of HTL students are consuming insane amounts of alcohol and doing stupid things in the workshop.

Oida, geh ned in die HTL, do weast nur depressiv.
