My grandpa’s “triple pun”

This joke holds a special place in my heart. My grandpa told me it and I never forgot it. About 2 years later when I brought it up to him, he didn't remember it. So I told him the joke and he peed himself laughing … At his own joke.

"Why did the man ask for his eggs Benedict to be served on a hubcap?"

"Because there's no plate like chrome for the hollandaise"
