Fire in the hole! Or so, that might just be your battle cry at the office each morning, as you prepare for the day’s “war” ahead with dreaded office politics hanging over your head. The rest of the mugs at the office would surely make way for the extremely manly $16.49 Grenade Mug, although the entry price does seem to be rather high at first glance. Still, the Grenade Mug does not discriminate just like an actual grenade won’t kill selected people – it will be able to handle hot, cold and lukewarm beverages without skipping a beat. I sure as heck hope that you will be able to concoct an explosive drink to make sure that this bad boy is worthy of the liquid within!
