Guess what pun people are making after Trump joked about his penis during a presidential debate?

During last night’s Republican debate in Detroit, Michigan, Donald Trump, the Republican frontrunner for President of the United States, made a joke about the size of his penis.

Trump guarantees there is no problem. https://t.co/I6OxUmLuNE

Naturally this led to many people on Twitter making the same joke about Don’s dong, which referenced the fuss Trump caused when he questioned the authenticity of President Obama’s birth certificate.
