25. Sean Astin as Mikey Walsh, The Goonies (1985)
We would never dare disrespect Mikey, nor the rest of the adventurous kids in The Goonies, but if you allow yourself to see things from older brother Brand's (Josh Brolin) point of view, a case can be made that Mikey is one especially annoying younger brother. You're tasked with watching him all day, his friends are always in the crib, and, to top it off, he steals a kiss from cutie Andy (Kerri Green) that's clearly meant for you. Considering that Brand is always working out, he could give Mikey the supreme dead-arm he, to be fair, kind of deserves.
