I have every episode from previously ...
... is it me, or do they seem "smarter" now?
Yes they seem "smarter". Like while critiquing LMFAO, Beavis said "ya know, with the economy in the toilet, and people losing jobs, and these buttmuches are spraying champaign everywhere!". And while watching 16&pregnant, beavis says "ah..so she isn't a bad actor...just a bad person"
Butt-head said during "Jersey shore" while snooki was making a "hook up chart", "I bet if she keeps going, they will find the source of syphlis"
I'm glad it is still "relevant" in its humor. My 12 year old daughter seems to like it. But then again, I had the entire series of "Daria" on dvd and she loved that show and she was about 10 at the time.
