Baby Jeff 

A smaller variant of a Jeff but less cool and can not make a British Royal Guard laugh in 3.7 milliseconds but in 3.9 milliseconds. The only advantage a Baby Jeff has over the Jeff is the ability of P90X. Although there seems to be an inherent rivalry, the reality is there is a close fellowship none can measure, "heterosexually" of course.

Person 1: Who you goin wit? Baby Jeff?

Person 2: What?! Nah! Jeff!
