Unbelievable

A couple had gone for a holiday to a famous tourist spot. It was then Puja vacation. The town was jam-packed with tourists. It was doing roaring business. All the hotels, guest houses and boarding houses were full. The couple knocked from door to door, but to no avail, not a single room vacant. At long last they got a room on the first floor of an old dilapitated wooden building at the far end of the town, adjacent to the railway tracks.
Dusk had set in. Leaving his wife in the room, the gentleman went out to purchase a few essential items. Travel fatigue and the tension in search of accommodation compelled the lady to throw her tired body on to the soft comfort of the bed. The whole day's fatigue brought drowsiness into her eyes and she had almost fallen asleep when a speeding train went roaring past along the adjacent railway tracks. The reverbaration shook the old wooden structure so violently that she was thrown off the bed. The lady somehow managed to steady herself and lay down on the bed once again. A few minutes later another train passed, again the violent tremor and again she was thrown off the bed.
This unexpected harrassment and discomfort naturally enraged her. With extreme agitation she ran down the wooden stairs to the manager's room and shouted at the manager, "What sort of hotel are you running ? What room have you given us ? Every time a train passes by I'm thrown off the bed."
The manager naturally objected, "The hotel is not classy, I won't deny that. The room is also beside the railway tracks. And people have stayed in that room before. But no occupant has ever complained that he was thrown off the bed everytime a train passed."
Hearing this, the lady became more agitated,"Do you mean to say I'm lying ? Such audacity you have ! You come with me, and I'll show you." She caught hold of the manager's hand and pulled him up to her room. Then looking out of the window she said,"A train is there at the station; signal is down, the train will come any moment now. Lie down on the bed. Let me see whether you're thrown off the bed or not."
The manager didn't get any scope to express his objection. He had no option but to lie on the bed.
At that fatal moment the husband entered the room. He was stupefied to see the hotel manager lying on the bed. The manager was also dumbfounded at the sudden turn of events. The husband shouted, "What the hell are you doing on my bed ?"
The manager hesitated at first, then stammered, "I know you won't believe it, nobody will. The truth is I'm waiting for the train." Luck favoured the manager. Because, just then the train rumbled past the adjacent railway tracks, and the manager's full efforts to hold on to the bed went in vain, and he was thrown off on to the floor. He got up and limped out of the room, dusting his clothes.
