Simple graphics that are timely and likely targeted to specific locations/stores.
These GIFs can include captions of any kind that are related to the video. Most would probably be funny. I.e., a "Monday graphic" could include the sleepy dog with some sort of text like, "Case of the Mondays" or something similar. Friday could be the same but with an energetic and fun GIF. Video content can be user-submitted or can be pulled from web locations (all of which would be free and allowed to be used commercially, of course).
Style 2: rather than having text in the white area, just make the video box larger and put the Loyall Life logo. Say whatever you want to say in the actual post's caption/comment.

Crazy, but could work!
This concept can also be used with movement as a GIF or looping video:
