Write a sentence that uses quotation marks indicate sarcasm or irony

Irony is the opposite of what something means which is same as sarcasm

Here's an example sentence.

The girl laughed as her father, the "fitness expert", struggled to do a push up.

This shows sarcasm and irony because if her father calls himself a fitness expert, then why is he struggling to do one pushup. This is the opposite of being a fitness expert.
