What's a joke that's so stupid it's funny?

From my 60 year old Mexican father:

A whole bunch of 80 year old men gathered for their weekly lunch.

The cockiest of them all says "This week, I made love to a lovely gringa, so blonde and so pretty." They are all amazed, except for the short pudgy guy in the corner who says "But how'd you do it, man?" "Shhh, it's my secret," he replies.

The next week, the same man says "This week, I made love to a lovely black woman, so tall and so fit." They are all amazed, except for the short pudgy guy in the corner who says "But how'd you do it, man?" "Shhh, it's my secret," he replies.

The next week he goes "This week, I made love to a lovely Asian woman, so smart and so cute" They are all amazed, except for the short pudgy guy in the corner who says "But how'd you do it, man?"

"Well...do y'all really want to know?"

They all say "Yes! Tell us!"

"Fine I'll tell you."

They open their eyes wide - the suspense is killing them.

"I lied."
