If your place of employment is anything like mine, not a whole lot of "work" actually happens the day before a holiday. So, being a bit tired (and/or hung-over) wouldn't really matter as much as usual. Would your boss really mind if you showed up with blood-shot eyes, whipped cream in your hair and smelling of $1.25 beers? I'm calling out all of the peeps; let's show up in force and party like rock-stars! You can do it!!!
