xD it's still my all time favorite in the series 
How could i forget the Courtney Gears music video 
and Ratchet twerking after it!
To this day i still sing it in my head :P
It's really hard to pick an all time favourite from UYA since so many cutscenes were hilarious,i'd say the cutscene where ratchet says a speech out about Qwark when they think he's dead xD,even when I look back to the cutscene now i still laugh
