The Brothers Chaps are releasing a 3-disc set with the first 100 Strong Bad Emails. Tons of extras... commentaries, all the original easter eggs, behind-the-scenes material, puppet videos, music videos, karaoke, etc. It's all-region, too, so it's probably for sale for most places.
It's on sale starting this week.
