Which makes you wonder what he's referring to here.....

The size of his brain?

The amount of respect he has for the office of President?

His knowledge of American history?

His understanding of geopolitics?

The number of books he's read?

The amount of tax he's paid?

The time left before they impeach him?

The size of his weenie?

Oh, and he also said that a longer tie makes you look thinner.

Nope, can't say it does.

Maybe it's compensation for something...
