We were also warned about swallowing chewing gum...and when we were kids we used to sing that song all the time...lol
Me too...that's why it came straight to my mind and I had to share it. One thing I remember in school is finding wads of chewed gum on the underside of most desks I sat at...I guess we were all told not to swallow our gum.
Yes I remember that with the desk chewing gum...my school friends' mother was a school cleaner and they were always having to look for gum under the desks
