Do you get it?

Harold is 76 and lives in a senior citizen home.

Every night after dinner, he goes to a secluded garden behind the
center to sit and ponder his accomplishments and long life.

One evening, Mildred, age 75, wanders into the garden. They begin to
chat, and before they know it, several minutes have passed.

After a short lull in their conversation, Harold turns to Mildred and
asks, "Do you know what I miss most of all over here?"

She asks, "What?"

"SEX!!" he replies.

Mildred exclaims, "Why, you old fart, you couldn't get it up even if I held a
gun to your head!"

I know," Harold says, "but it would be nice if a woman could, you know, just hold
it for a while."

" Well, I guess I can oblige," says Mildred, so she unzips his trousers, removes
his manhood and proceeds to hold it.

Afterward, they agree to meet secretly each night in the garden where
they would sit and talk and Mildred would hold Harold's manhood.

Then, one night, Harold didn't show up at their usual meeting place.
Alarmed, Mildred decided to find Harold and make sure that he was OK.

She walked around the senior citizen home where she found him sitting
by the pool with another female resident, Ethel, who was holding Harold's
manhood!

Furious, Mildred yelled, "You two-timing creep! What does Ethel have
that I don't have?"

Old Harold smiled happily and replied, "Parkinson's...."
