"Zoo or False" is an awful How I Met Your Mother episode, but the ending was great. In this episode, Marshall lies about getting mugged by a monkey. It was annoying how he keeps changing his story to being mugged by a monkey or mugged by a person. I don't care if he was mugged my monkey. And I didn't care for Barney's plot because he was a complete hypocrite. He lies to women all the time and he gets upset when they lie to him. But I did enjoy when Barney said that "a lie is just a great story that someone ruined with the truth". Now I did love the end of this episode where they bring in the monkey from the zoo on Robin's show and the monkey goes crazy. I give this episode a 5/10.
