It seems they stopped adding episodes on Paramount+
Yes, but more are currently airing on Comedy Central UK, including:
Eating Contest
1-900 Beavis
Water Safety
Figure Drawing
Butt is it Art?
Manners Suck
Radio Sweethearts
Killing Time
Safe House
Beavis and Butt-Head’s IslandI wonder why they stopped though
Possibly copyright issues
Nothing to suggest this, as there are other episodes with duplicated music videos they haven’t aired on P+.
They’re likely to add more in the build up to season 10, but they’re a long way off from a full set.
