An Oxymoron is defined as a phrase in which two words of opposite meanings are brought together....
Here are some funny Oxymoron :
1) Clearly Misunderstood
2) Exact Estimate
3) Small Crowd
4) Act Naturally
5) Found Missing
6) Fully Empty
7) Pretty Ugly
8) Seriously Funny
9) Only Choice
10) Original Copies
And people say the Mother of all Oxymorons is-
11) "Happily Married"
