除了自嘲式和三词排比式（rule of three）幽默，另一种常用的幽默的方法就是利用对比。也就是通过对比今夕，中外， 老少等产生强烈的反差，制造笑点。
在Ellen show一期中，Ellen 是这样表现今昔人们交友方式的区别：
“For those young people out there, you don’t believe this, but in the past in order to have a relationship, you have to talk to someone…IN PERSON…. And you had something called a CONVERSATION.
When someone rejected you, they had to reject you IN PERSON. And you can see their expression. … Kids, you call it “Emoji” and we call it “Face”
In 1980, a happy meal was when father shared funny stories around the table.
Today, a happy meal is what dad buys at McDonald’s.
In 1980, when fathers entered the room, children often rose to attention.
Today, kids glance up and grunt, “Dad, you’re invading my space.”
演讲中也有通过对比来产生幽默的例子，比如2017世界演讲大赛冠军Manoj Vasudevan 在他获奖演讲“Pull Less, Bend More“ 中，就用幽默的对比的方式来表现他和太太之间差异巨大，（还有点自嘲成分）：
“She likes outdoors; I like indoors.
She likes swimming; I feel drowning.
She likes cooking; I’d like to tell her how I’ve missed my mama’s cooking. “
“When she wants to go out, I join her.
When she wants to swim, I join her…at the shallow end.
When I became nice, she became nicer.
Soon she started to cook better than mama.”
“According to most studies, people’s number one fear is public speaking. Number two is death. Death is number two. Does that sound right? This means to the average person, if you go to a funeral, you’re better off in the casket than doing the eulogy.”
