You'll be singing the tune all day...

OMG! Check out our favourite YouTube of the week!

The cutest craze sweeping Youtube is itsy bitsy animals having a chomp on their favourite snack to the (very annoying yet very catchy) tune 'nom nom nom nom nom nom nom'.

Viewers have become so obsessed with the nom nom tune (which is the universal word for yum) that they've started pasting their own funny versions. But what could be better than cute hamsters having a nibble on some brocolli? Not a lot.

So check it out, and then try NOT singing the song for the rest of the day. We bet you fail.
