Here's one that I'm surprised is not already in the Goodword Dictionary.
dun·der·head (dŭndər-hĕd′)
n.
A dunce.
[Perhaps Dutch donder, thunder (from Middle Dutch doner; see (s)tenə- in the Appendix of Indo-European roots) + HEAD.]
dunder·head′ed adj.
dunderhead (n.) 1620s, from head (n.); the first element is obscure; perhaps from Middle Dutch doner, donder "to thunder" (compare blunderbuss).
blunderbuss (n.) 1650s, from Dutch donderbus, from donder "thunder" (Middle Dutch doner, donder, from Proto-Germanic *thunaraz; see thunder (n.)) + bus "gun" (originally "box, tube"); altered by resemblance to blunder.
