Video footage of identical twins sitting in their high chairs and dancing to their father's guitar has become an online hit.
At the start of the 30-second clip, the 11-month-old girls are calmly sitting and eating stray peas.
However, once their dad begins to play, the sisters turn and stare at each other with wide eyes and bags of enthusiasm.
Clearly recognising the song, they are soon beaming with delight and boogieing to the stream of the instrument.
The online community has been stunned by the sisters' display of euphoria and the cuteness engendered in the video.
One viewer pinpointed: "That moment when they look at each other with joy and 'no way he's playing our favourite song'."
Another impressed commentator wrote: " This makes me smile every day in this craptastic world!!"
