An Easier Event Manger/Registration Plugin

It seems like every event registration plugin makes the users fill out a long form. Can this be even more basic? One that has an event, and a member of the site can just click a “register me” button after they are logged in and they don’t have to fill anything else out? No forms, just 1 click and they’re on the list, as long as they’re a member of the site. I run an stand up comedy open mic, and I have an event registration plugin on Geeklog that does this. I want to switch this site over to WordPress and have this same functionality for the users. Seems like all the event manager plugins make users fill out a big form to register. I need a simpler one since they sign up for these events weekly and they’re all used to just clicking “register me” and being done.

Thanks!
