Is it haram to laugh at big chungus?

Salam alaikum, this question seems weird but listen to my story. Every day after coming back from school I look at an image of big chungus and laugh hysterically for around 15min, it's the only time of the day when I feel happy. One day my mother insisted on knowing why I was laughing, after she saw the picture of big chungs she immediately turned off my computer and told me that what I was doing was haram and she refused to explain why.
