Lol, Newfish...if I have Celtic elements in my accent does that make me Celfish (think Seltik not Keltik). That scene is a classic...I especially like the very end where Lancelot asks for a push. So many classic, classic lines: "Are you suggesting coconuts migrate?", "You must cut down the mightiest tree in the forest wiiiith...a herring!"...etc., etc., etc. ad nauseam. My dad would have been 85 today. My son's birthday is tomorrow, for a brief moment I thought he would share my dad's birthday. My ex wife was induced on the 17th, but it didn't work so I thought, "Great! We can come back tomorrow and have the baby share my dad's birthday!". Unfortunately, the hospital didn't have an anesthesiologist on duty the 18th so we had to go back on the 19th.
I know about the laughing fits. The Grail, Young Frankenstein, High Anxiety, and The Naked Gun have all induced uncontrollable laughter in me, Caddyshack, though I love the movie, not so much.
In the words of Sean Connery, "God shave The Queen". Have a great Victoria Day! (Great song by The Kinks btw ("Victoria"). Peace and love from The Great White West. :-)
