There are two suggestions for further studies. One is that there should be a collection of authentic jokes which contain more complex humour such as incongruous genre and incongruous world in the Linguistic humour structure spectrum by Obrst (2012). The other is that it is advisable to have a deep look into the role of socio-cultural competence in joke performance and creation in the workplace of tour guides, international tour guides in particular.
In conclusion, it has demonstrated that humor can be trained. The study has challenged the traditional conception that sense of humour is in-born and it is impossible to train humour, especially for Vietnamese tour guide students who learn English as a foreign language. The study has shown that, through training, the tour guide students who learn English as a foreign language in the study can develop their ability to comprehend humor and recite English jokes. Furthermore, being able to make sense of humour in English jokes has helped these students develop their language and communication skills with humour which in turns could help improve their English language learning through English jokes. This is a new contribution of the present study. Eventually, the study has achieved a real breakthrough in training a highly-skilled workforce for the tourist industry.
