Tally-whacker

Bill Clinton after playing a round of golf with Supporters, notices
Donald trump standing in an adjacent urinal.

Suddenly Bill looks down and notices that Donald was quite well endowed.

"Damn, Donald," Bill said, "How did that thing ever get so big?"

"It's like this, Every night, before I go to bed, I smack it against the bed post ten
times. That's all it takes."

"What a good idea!" said Bill.

"Hillary's been ignoring me lately; this could really perk up our love life."

Later that evening in the White House bedroom, with Hillary already
asleep, Bill decided to try it out. He undressed and began to bang
his ol' tally-whacker against the bed post. This woke Hillary, who
turned over, giggled, and said in her most romantic voice,

"That you, Donald?"
