Last year I had a most fun assignment in which an entire team at LOBO was tasked with coming up with twitter reply images for every situation in which someone would tweet them the taco emoticon + any other emoticon. I did a share of them, including several gifs, at a slightly fast pace in order to produce as much as possible in a small time frame. Below you can see many, as I selected my favourite of them.
