Well naturally the best skit is all up to each individual.
But if you want some of our honest opinions I'll start the ball rolling.
There are some really good skits that stand out for me. Some examples are:
A bunch of whatnot skiers singing Tumbling Tumbleweeds and crashing into trees, each other etc. all the time.
The Electric Mayhem performing When the Saints go Marching in with Hal Lyndin while trapdoors are opening up under them.
Behemoth and Shakey Sanchez performing a very weird duet version of I've got you Under my Skin.
A gingerbread man singing Sweet Gingerbread Man while four larger ones dance in the background.
A band of Viking Pigs singing In the Navy.
All of which are very good but the best skit of all for me personally is the Pigs singing The Happy Wanderer.
Anyone else want to share their favourite skit or skits?
