Jamie Moyer may be 15 years older than Roy Halladay, but the two were teammates on the 2010 Phillies. That doesn't, however, prevent Halladay from poking fun at Moyer for being so much older, as evidenced by his costume at an '80s-themed party last week.

Yep, Halladay's costume is of Moyer as a rookie on the 1986 Cubs. Moyer would go on to pitch in the majors as recently as 2012, racking up nearly 700 appearances and over 4,000 innings on the hill.
