Three business associates joke

Three business associates, an Igbo man, a
Yoruba man and a Chinese man, went to eat
lunch together at a restaurant in Surulere.
While in the middle of their meal, a fly came in
through the window. It flew across the table
to where the Igbo man was but he just
waved his hands to chase it away.
The fly then went to where the Yoruba man
was, he also chased it away.
Finally, the fly then went to where the Chinese
man was and was flying close to his ears. The
Chinese man looked at the fly for sometime
and then grabbed it, put it in his mouth and
swallowed it.
The other men saw this but just kept on
eating.
About Five minutes later, another fly came in
and flew to the Yoruba man who just chased
it away again.
It then flew on to the Igbo man but this time
he did not chase the fly, he looked at it for
sometime and then grabbed it. He then
turned to the Chinese man and asked "how
much you go buy am?"
