When Marie Venezia got a tattoo of a knife on her arm, she had no idea how her father was going to react.
The 18-year-old art student from Phoenix, US, was on a trip to the zoo with him when he finally spotted the inking on her forearm.

Venezia took to Twitter to share her father's hilarious reaction and her tweet has since been shared almost 62,000 times.
