Mixing Mashups (Thing 5)

I had seen these faux-motivational posters on-line, but didn't realize they were/could be mashups. Much of the other stuff also had a familiar feel to it (comic captions, posters, etc.) There's an ironic nature about a fair number of the mashup options, it seems to me, which appeals to me and a number of my students, I gather.

Of course the use of mashups has classroom implications... but I can see lots of ways they could help with the various communications (staff, parents, family) we all find ourselves needing to do.
