Random Fact of the Day:

Although the R sound is made mainly with the lips in standard American English, in most languages and even some English dialects, the R is pronounced almost exclusively with the tongue, similar to the L. This accounts for the R to L shift in old nicknames (Mary to Molly, Sarah to Sally, for example) and the difficulty new English learners have with our Rs ("flied lice", anyone?); as well as the inability of most English speakers to roll their Rs.
