If a narwhal sticks a child with its horn then you have to admit that it exists. We know some of you have been doubting narwhals and whether they're real. Well now your kid is a kabob, so do you believe they exist now? I suppose you do.
Oh, and the child we had to narwhal stab to prove they exist - that's your son (そん). Maybe you should have listened and kept your son out of the Narwhal Danger Zone (ぞん) after we warned you about it.
