Notes:
07:24 - References a Japanese period drama called "Mito Kōmon". For reference to the scene in general - • 【水戸黄門】この紋所が目に入らぬか！！
07:54 - This clip comes from this stream - • 【マインクラフト】エンチャント沼を終わらせる...
I left "Koumon" untranslated as it 'could' mean a number of things. In this case, Watame most likely mixed it up with the name of the show, however, the most common meaning devoid of any context would be "anus" which in these circumstances, would obviously result in the chat to burst out laughing.
