Two Men And Two Women Are On A Train.

There is a mother and daughter on their way to have a holiday, and there is an old general and his valet, a young sergeant. The train goes through a tunnel, and everything is dark. There is a mwsshk! and a smack! and the train leaves the tunnel.

The mother thinks, "that young man stole a kiss from my daughter and got slapped for it!" The daughter thinks, "that young man tried to kiss me, and kissed my mother by mistake!" The general thinks, "that upstart pup steals a kiss and I get slapped for it." The sergeant thinks, "not bad! I just kiss my hand and get to slap the general, and here comes another tunnel!"
