This morning I went to Wal - Mart to buy deodorant and soap . Funny that I should simultaneously run out of those things . While I was there , " Who Let the Dogs Out " was playing . It was playing when I came in , and I swear , it went on for like 6 minutes .

Give answer the following question using evidence from the above passage: Why did they buy those products in specific ?
They need them to keep themselves clean .
