Amazing footage of a husband and wife announcing to the man's dad that he is "finally going to be a grandfather" in a particularly unique way.<br /><br />The video, filmed in Pennsylvania, USA in July this year, shows the couple revealing the pregnancy in the form of a "Whisper Challenge", whereby the grandfather-to-be wears a pair of headphones and has to try and read their lips. <br /><br />"He was absolutely terrible [at the whisper challenge]," the filmer later wrote online. <br /><br />"However, he really enjoyed the Blue Grass music in his ears." <br /><br />"To say he was excited, is such an understatement," he continued, referring to his reaction once he realised what they were trying to tell him. <br /><br />The couple have been together for nine years and married for three and the man's dad has apparently been bothering them to have a baby for quite some time.
