We actually had to specifically take a good half hour to get the giggles out after "the smell of foreskin" the first time we rehearsed it. The giggles are infectious too. If I get them our lead singer gets them so I have to just sort of walk over to my amp... which is problematic if I have to do harmonies.Oh, jeeze. We learned this one years ago specifically for weddings. We were rehearsing it for the first time and trying to be funny, I replaced the line "The smell of your skin" with "The smell of foreskin", cracking up the whole band. It was all we could hold it together through that song for the actual wedding and anytime we've played it since. Hell, I'm giggling as I'm writing this. I really need to grow up.
