A man was driving down a street along Alausa, having just finished answering a call, when a policeman, suddenly, opened the passenger door, entered and jam-locked it.
(The door lock is faulty)
As usual, he wanted 'something' from the man for calling while driving...
Suddenly, he saw the big Rothweiller dog, Jackie, at the back seat of the car, with tongue stuck out, spittle dripping and fangs barring, staring fiercely at him.

Policeman: (Shaking)
Ah! You carry dog?

Man: (with bone face) Yes, I carry dog. Dat one na offense?

Policeman: (Feeling uncomfortable)

Man: From hospital.

Policeman: Ehen! you sick?

Man: No, na person wey the dog bite we go see. The person almost die sef.

Policeman: (Terribly shaken by now)

Man: Na so im dey do if e wan bite person.

Man: Yes nah, no be my dog?

Policeman: (Sweating)

Man: How you take enter?

Policeman: Abeg! Na since I dey try open am, but e no open.
(The dog was now getting impatient and gave a small growl, its tongue almost touching the policeman's left ear).

Policeman: (Now sliding forward)Oga, I take God beg you, open the door for me make I comot. I no go collect anythin from you.

Man: How much you go pay me?

Policeman: Ah! I neva hustle anythin since morning. Na only N1,000 dey wit me.

(The man looked back at the dog).

Policeman: Ok ok ok ok ok, e reach N2,000. The oda N1,000 na my wife own, but I go give you join.
(Now, close to tears as the dog was becoming really impatient)
Oga, I be......g, Oga, sorry. Take the N2,000 make you open the door plssssssse!
