Dispatch 100 papers showing scoop maybe? (3,5)
I believe the answer is:
ice cream
'scoop maybe?' is the definition.
(measure of ice cream)
'dispatch 100 papers' is the wordplay.
'dispatch' becomes 'ice' (both can mean kill).
'r00' becomes 'c' (Roman numeral).
'papers' becomes 'ream' (I've seen this before).
'ice'+'c'+'ream'='ICE-CREAM'
'showing' acts as a link.
(Other definitions for ice cream that I've seen before include "Hot day treat" , "Sweet frozen food" , "Cold snack" , "Cool confection, sweet frozen dessert" , "Cool summer confection" .)
