Thursday marked the last time Barack Obama will celebrate his birthday as President of the United States.
Happy 55th birthday greetings started rolling in early on Twitter. Vice President Joe Biden was among the first and, hands-down, sent one of the best.
He tweeted a picture of the friendship bracelets Obama was seen weaving in a Buzzfeed video about five things that are harder to do than registering to vote.
Someone else close to the president sent best wishes, too.
And, birthday wishes from another Oval Office occupant.
Uproxx reminded the Commander in Chief of his mic drop at the White House Correspondents’ Dinner in May.
Some people dug deep into the archives ...
While others showed off their GIF skills.
Remember when you were on the cover of Jet magazine, Mr. President? Jet remembers.
But no offense. You should probably leave the singing to someone else.
