  • This function displays the latest comic from xkcd.com. One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic. To get a random xkcd comic, I also use the following: xkcdrandom(){ wget -qO- dynamic.xkcd.com/comic/random|tee >(feh $(grep -Po '(?<=")http://imgs[^/]+/comics/[^"]+\.\w{3}'))|grep -Po '(?<=(\w{3})" title=").*(?=" alt)';}

Perfect House Of Pugs acquired a passion for animals, and the Pug puppy in particular, at a young age since I grew up in a house with lots of dogs. It was a natural ability to know how to grow, nurture, and care for animals. I knew what the future held when I met my wife, who essentially had the same enthusiasm as I have. Being a breeder is more of a passion for me than a profession since I get to witness people's faces light up when they successfully adopt a pug puppy from our facility. It is not possible to find happiness in anything else. PLEASE VISIT OUR WEBSITE LINK BELLOW FOR MORE INFORMATION ABOUT PUG PUPPIES.
