The Gilsbert way of How not to tell a joke

Gilsbert at onsite:

“Hey I am Gilsbert”
“I am Tan”
“Is it so? Doesn’t look like it”
“err..means?”
Looking at his reaction, quickly back tracks into a different conversation.

After sometime, while trying to resell the same joke.
“So Tan..you sign by cause”
“err..means”
This time wanting to clear the point, Gilsbert puts in “extra” effort
“Sin/Cos”
“I didn’t get you”
“Not a maths guy is it?”
“What??”
“Sorry..” muttering to himself walks away.

While leaving for the day,
“Ok Tan..catch you tomorrow”
“Sure man”
“What time you are planning to start?”
“Not sure..will take a couple more hours”
“Wow..you ARE a workaholic” sensing an opportunity “may your spirit never tan”
“err…sorry. Couldn’t get the last part”

Oh..Come onnnnnnnnnn
