San Juan, Puerto Rico Puns

My housemate was talking about her upcoming trip to Puerto Rico and saying that she had to transfer flights in San Juan.

"But why would you continue after San Juan?"

"What do you mean?"

"You know what they say, when you've San Juan, you've seen 'em all!" Chuckles to self for the next five minutes

So I'm visiting Puerto Rico with my family (dad, mom, sister and I). One of the main attractions in San Juan is the Capitol building. After walking around for a while, I had to go to the bathroom. This is the exchange that ensued:

Me: Have you seen any bathrooms nearby?

Dad: Nope, no bathrooms around here.

Me: Ummm, why not?

Dad: Because all politicians are full of shit!

Groans were had all around
