.............to attend a conference. At the station, each Texan buys a ticket, but they notice that only one Cajun buys a ticket.
"Don't you all need tickets?" they ask.
"Mais Non," reply the Cajuns, "One is more dan enough, boo."

Once they board the train, the Texans take their seats and notice that all 3 Cajuns cram themselves into a toilet. As the conductor passes through the car, he knocks on the toilet door and says, "Ticket, please." The door cracks ever so slightly, a hand passes out a ticket, and then the door quickly closes.
"Ahhh... very clever" think the Texans.
After the conference, the 3 Cajuns and the 3 Texans are again at the train station for the return trip. Since the Texans are now so
'money-wise', they smirk as they only purchase one ticket... but then they notice that the Cajuns don't buy a ticket at all.

"How will you get back without even a single ticket?", they ask.
"Mais, we don need dat, us on de back trip!", say the Cajuns.
Once they board the train, the 3 Texans cram themselves into the largest toilet (naturally), and the 3 Cajuns ease into another toilet. As the train begins to move away from the station, one of the Cajuns leaves the toilet and knocks on the
door of the Texans' toilet and says, "Ticket Please."

Mais oui, dat was another bon temp

Didn’t know there was a difference between a Texan and a Cajon
