I wonder if you get a discount at the ice cream shop down the street if you have a party bigger than 100  
((This wasnt made in response to a question; rather, its simply a fun project I worked on over the past week with Ask Spiiike and Spike Replies. We tried editing the audio to replace the Billies with Spikes, but that didnt work out so well, so we left it be, haha. It would be pretty hard to get a Billy West sound-a-like to fill the role quickly enough. :P  
Anyways, heres the list of blogs we worked to get in! We tried to get as many blogs as we could into this, and also tried to get every blog featured a door and a drawn/animated cameo as well (we didnt manage to get all of them a door though; sorry about that!), so see if you can find all of them!
