Most funny joke of the century

An Igbo engineer can't find
a job so he opens a clinic
and puts a sign outside 'GET
TREATMENT FOR 20k - IF
NOT CURED GET BACK 100k
A lawyer thinks this is a great
opportunity to earn
100k and goes to the clinic...
Lawyer: "I have lost my
sense of taste"
Igbo man: "Nurse, bring
medicine from box no. 22 and
put 3 drops in patient's
mouth"
Lawyer: "Ugh..this is
kerosene"
Igbo man: "Congrats, your sense
of taste is
restored.
Give me 20k"
The annoyed lawyer goes
back after a few days to
recover his money...
Lawyer: "I have lost my memory. I
cannot
remember
anything"
Igbo man: "Nurse, bring
medicine from box no. 22
and
put 3 drops in his mouth"
Lawyer (annoyed):
"This is
kerosene. You gave this to
me last time for restoring
my taste"
Igbo man: "Congrats. You
got your memory back. Give me
20k"
The fuming lawyer pays him,
and then comes back a
week later determined to
get back 100k.
Lawyer: "My eyesight has become
very weak"
Igbo man: "Well, I don't
have any medicine for that,
so
take this 100k"
Lawyer (staring at the cash): "But
this is 20k, not
100k"
Igbo man: "Congrats, your
eyesight is restored. Give me
20k"
You can't beat an Igbo man
when its comes to money tru or
false?
