During a break in a class, a trainer receives an e-mail from a friend that contains a joke that would fit nicely with the next topic. The joke contains a questionable punch line that is related to cultural differences, but the members of the class do not appear to be part of the cultural group the joke might offend. The trainer should:

A.
go ahead and use the joke

B.
use the joke and explain how it relates to the content

C.
use the joke but preface that no one should be offended

D.
not use the joke because it is questionable
