"...do you know the Army's turning down boys because they're not in shape?"

I find a great deal of humor and irony in that line, but I can't recall which episode it is from. Can anybody out there help? Thanks!

(I'm new to this board, but years ago I used to be a regular visitor to the TVLand boards. But that was before they decided they wanted to be like every other network and I was forced to purchase several of my faves on DVD.)

Have a great day!
