I switched it to hours and put a notice at the top of my site:

TTD Offsite - Today the TTD Staff will be off having a barbecue (thank you to all the donators on this site!). We'll be having a little beer, and a little wine, along with some fine food courtesy of Mr. Aaron and Ms. Heather. We will be checking in every once in a while, but I'm not sure what our state-of-mind will be like at the time, if you know what I mean! So, while we are gone, we have allowed a couple of trusted users, Mr. Wolf, and Mr. Possessed, and Mr. {insert username here} to watch over the users and if you misbehave, you may find yourself banned by them since they now have banning priveledges. So.... Be Good!

I've so far, in one hour, we have had 8 users ban themselves. I haven't had any comments yet on my subtle hint that we were using donations (our site runs on donations) to have the barbecue.

Thank you for this!

edit to add:
I created a new plugin, April Fools, at postbit_display_complete with the following code:

eval('$template_hook[postbit_userinfo_left] .= " ' . fetch_template('postbit_april_fools') . '";');

and then created a new template, postbit_april_fools, with the following code:

<div class="smallfont"><a href="/forums/ban.php">Temporarily Ban $post[username]</a></div>

That inserted the link into the postbit for them to ban the users.
