I doubt it was this, but I hope Obama left one minor prank on his way out, like a whoopie cushion, or an upside down desk drawer.

Obama leaves a letter on the desk for Trump's first day. It reads:

"Mr. President,

On this, your first day in office, congratulations again on your victory. Although it's clear to us both by now that we may never see eye-to-eye on many important issues, I want to express my hope for your success in this new position. Very few people will ever understand the challenges endured while carrying the weight of a nation, if not the entire free world, on one's shoulders like we do. Along those lines, I humbly offer you my full support, putting aside whatever differences we might have, in the interest of serving our shared and highest value, the well-being and advancement of this great country. Should you ever want it, I am prepared and willing to give whatever assistance possible with utmost diligence and discretion.

We're all counting on you. Good luck!

Sincerely,

Barack Obama

P. S. I left a little something in the upper right-hand drawer just to show there's no hard feelings."

After reading it, Trump opens the drawer and hundreds of marbles spill out along with a note card.

I think this why he's so mad at Obama.

I never stopped saying it lol
