Broad City is consistently funnier, but IAS definitely has its moments. The sketch with Paul Giamatti as god was just end-to-end gold. Loved the little throwaway "shrimp you've been prawn" at the beginning (which I would bet money was a Kyle Dunnigan joke).
I need to check out Broad City again! I watched the first episode and thought it was "made the jump from web series to actual TV show too soon." But I'll give it another try!
