From the Beginning (song) Puns

My dad, sister and I were driving home the other night when a U2 song came on the radio. He asked us if we knew what the song was about (Sunday Bloody Sunday). I knew, and mentioned it's unfortunate source. My sister then asks from the back seat "Are U2 Irish?" to which my dad responds "Nope! We're Canadian!" and then begins laughing so hard that he is practically in tears and snorting. He didn't stop for a good 2 or 3 minutes. My sister and I just shook our heads slowly.
