Leo's jokes echoed through Donnie's laboratory, you pretended to laugh in amusement, just out of kindness and to not make Leo feel bad and Donnie knew it.

When Leo finally left the lab, Donnie looked at you a little irritated.

"That wasn't even funny, if you like his jokes, do me a favor and listen to them outside of my laboratory." You knew that after the failed experiment you were both working on had put him in a bad mood and even more so, listening to Leo's jokes for a few good minutes.
