Since work is very slow today I've had the opportunity to look back and reflect on slides I've created for business presentations past. A key to the humor in this one is the fact that the man purchasing a frankfurter is a Buddhist monk, which is indicated by the graphical convention of having both of his feet facing backwards and to his left. Also, this is from a few years back so I can't remember for sure, but it may have an alternate punchline from the version which was ultimately delivered to the clients.
