Do you know who I am? 

A line often uttered by self-absorbed asshats who feel they are being wronged by someone in a particular situation. History often proves that these douchebags, who might have an extremely low level of fame that most people are unaware of, are being treated on equal footing with the rest of the general public. This angers them even more.

BOUNCER: You're going to have to leave this club, sir.

DOUCHE: Wait a minute, wait a minute...do you know who I am?

BOUNCER: No. Get the fuck out of my face.

Do you know da wae? 

Probably one of the most biggest memes of January 2018. This is said by a bunch of Ugandan warriors who play as Knuckles from Sonic together in a VRchat. They will keep repeating and saying the words "Do you know the way?' in a strong Ugandan accent.

"Do you know da wae?"
"I can show you da wae"

Wouldn't you know who won the pony

Implies that the previously stated is rigged; local wrestling promoter, as told by Jim Cornette, gave away a pony to increase ticket sales and, to avoid losing money, rigged the raffle to ensure his son would win the pony

Of course, that asshole was late again!
Oh, wouldn't you know who won the pony!
