When the volcanoe Mount Tavurvur erupted in Papua New Guinea on August 29, 2014, one onlooker calmly uttered the words "Holy smoking toledos!", when the sonic boom hit them. I just love the expression!

The behemoth Mount Tavurvur belched out a thick tower of ash thousands of feet into the skies above the island of New Britain early Aug. 29, and Australian taxi driver Phil McNamara got a front row seat to Mother Nature's show.

McNamara and his wife Linda were vacationing in the area when he heard that the volcano was ready to spit out its fury. The Queensland couple made a "spur of the moment" decision to get onto a hotel boat and take a closer look.
