The image has a stock photo of a chemist with Samuel L. Jackson's head photoshopped on, and he appears to be looking a graduated cylinder with some colored liquid in it.

Near the bottom there's the text "ah, yes".

Below it are two rows that look like they were copied from the periodic table, with atomic numbers at the top, then the abbreviation in the middle and the full name of the element at the bottom.

The first row of elements is Mo, Th, Er (molybdenum, thorium, erbium)

The second row of elements is F, U, C, K, Er (fluorine, uranium, carbon, potassium, erbium)

edit: corrected term to "atomic number"
