I would rather crawl through glass shards covered in lemon juice than have the displeasure of dealing with the IRS. I wish we could dissolve this whole bloated organization. I think sentient wallpaper could run this better. Gagging at the idea of how much taxpayer money is wasted on these mouthbreathers.
