Helm's "Untitled Demo Game" can be found here. It's one room and ends with an error message when you exit, and it probably won't work on a newer computer. Looks good, though.
An ancient joke game called Dan finds his beard can be found here.
A kind of joke game of a different nature can be found here: https://archive.org/details/kings-quest-for-orgy
It's very short and not the same as the real Quest for Orgy, which can be found here.
A couple of older games not in the database, but on the archive: Trapped with Hell: Cruisin' and Trapped with Hell.
Edit: I tried the two Trapped games only after posting the links, hence no comment then. These are made by a kid years back. There are threads ridiculing them about how bad they were, and indeed, they're not any good, and rely a bit on offensive language. But they're not difficult either, despite what's said in the old threads where people gang up to ridicule a kid's game (not one of the forum's finest hours), so for someone who wants to play through all the available AGS games, they are a five minute distraction each. Not worth the time of others than completionists and people who find bad games amusing.
