I found this in my collection (no, it’s not mine, but it is a colleague’s but he won’t be reading this so I’m safe). He has used a Spongebob figure in a scientific presentation. In my view this fails because (1) the clipart is very low resolution so looks very amateur and (2) because it’s redundant. You don’t need a picture of Spongebob to understand the concept of a sponge.
So in my view this slide is spoiled by the irrelevant and “humorous” (not) cartoon. It’s a bad slide anyway – the artwork could have been vastly improved with a little effort.
If in doubt, when it comes to clipart – DON’T!
